Add customisable EEPROM driver selection (#7274) 

- uprintf -> dprintf
- Fix atsam "vendor" eeprom.
- Bump Kinetis K20x to 64 bytes, too.
- Rollback Kinetis to 32 bytes as partitioning can only be done once. Add warning about changing the value.
- Change RAM-backed "fake" EEPROM implementations to match eeconfig's current usage.
- Add 24LC128 by request.

# EEPROM Driver Configuration
The EEPROM driver can be swapped out depending on the needs of the keyboard, or whether extra hardware is present.
Driver | Description
--------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
`EEPROM_DRIVER = vendor` | Uses the on-chip driver provided by the chip manufacturer. For AVR, this is provided by avr-libc. This is supported on ARM for a subset of chips -- STM32F3xx, STM32F1xx, and STM32F072xB will be emulated by writing to flash. Other chips will generally act as "transient" below.
`EEPROM_DRIVER = i2c` | Supports writing to I2C-based 24xx EEPROM chips. See the driver section below.
`EEPROM_DRIVER = transient` | Fake EEPROM driver -- supports reading/writing to RAM, and will be discarded when power is lost.
## Vendor Driver Configuration
No configurable options are available.
## I2C Driver Configuration
Currently QMK supports 24xx-series chips over I2C. As such, requires a working i2c_master driver configuration. You can override the driver configuration via your config.h:
`config.h` override | Description | Default Value
------------------------------------------- | ----------------------------------------------------------------------------------- | ------------------------------------
`#define EXTERNAL_EEPROM_I2C_BASE_ADDRESS` | Base I2C address for the EEPROM -- shifted left by 1 as per i2c_master requirements | 0b10100000
`#define EXTERNAL_EEPROM_I2C_ADDRESS(addr)` | Calculated I2C address for the EEPROM | `(EXTERNAL_EEPROM_I2C_BASE_ADDRESS)`
`#define EXTERNAL_EEPROM_BYTE_COUNT` | Total size of the EEPROM in bytes | 8192
`#define EXTERNAL_EEPROM_PAGE_SIZE` | Page size of the EEPROM in bytes, as specified in the datasheet | 32
`#define EXTERNAL_EEPROM_ADDRESS_SIZE` | The number of bytes to transmit for the memory location within the EEPROM | 2
`#define EXTERNAL_EEPROM_WRITE_TIME` | Write cycle time of the EEPROM, as specified in the datasheet | 5
Default values and extended descriptions can be found in `drivers/eeprom/eeprom_i2c.h`.
Alternatively, there are pre-defined hardware configurations for available chips/modules:
Module | Equivalent `#define` | Source
-----------------|---------------------------------|------------------------------------------
CAT24C512 EEPROM | `#define EEPROM_I2C_CAT24C512` | <https://www.sparkfun.com/products/14764>
RM24C512C EEPROM | `#define EEPROM_I2C_RM24C512C` | <https://www.sparkfun.com/products/14764>
24LC128 EEPROM | `#define EEPROM_I2C_24LC128` | <https://www.microchip.com/wwwproducts/en/24LC128>
24LC256 EEPROM | `#define EEPROM_I2C_24LC256` | <https://www.sparkfun.com/products/525>
MB85RC256V FRAM | `#define EEPROM_I2C_MB85RC256V` | <https://www.adafruit.com/product/1895>
?> If you find that the EEPROM is not cooperating, ensure you've correctly shifted up your EEPROM address by 1. For example, the datasheet might state the address as `0b01010000` -- the correct value of `EXTERNAL_EEPROM_I2C_BASE_ADDRESS` needs to be `0b10100000`.
## Transient Driver configuration
The only configurable item for the transient EEPROM driver is its size:
`config.h` override | Description | Default Value
------------------------------- | ----------------------------------------- | -------------
`#define TRANSIENT_EEPROM_SIZE` | Total size of the EEPROM storage in bytes | 64
Default values and extended descriptions can be found in `drivers/eeprom/eeprom_transient.h`.

Support for up to a single driver with room for expansion. Each driver can control 192 individual LEDs or 64 RGB LEDs. For more information on how to setup the driver see the [RGB Matrix](feature_rgb_matrix.md) page.

Support for an external I2C-based EEPROM instead of using the on-chip EEPROM. For more information on how to setup the driver see the [EEPROM Driver](eeprom_driver.md) page.
