This moves the ledbar driver to generic, to be also used by the ramips target.

The LEDs connected to the MCU are so-called smart LEDs and their signal is
daisy-chained. Because of this, the MCU needs to be told how many LEDs are
connected. It also means the LEDs could be individually controlled, if the MCU
has a command for this.

During GPIO initialization the pin state flips and triggers a reset of
the ledbar MCU. It needs to be moved through an initialization sequence
before working correctly.

Some versions of the ledbar MCU have a reset pin. It needs to be
correctly initialized or we might keep the MCU in reset state.

Or the comparison against a signed char is always true, because the
literal 0xaa is treated as an unsigned int, to which the signed char is
casted during comparison. 0xaa is above the positive values of a signed
char and negative signed char values result in values larger than 0xaa
when casted to unsigned int.

The read response is in the i2c_response variable. Also use %hhx format,
because we're dealing with a single char.

mtd->size will be overrided by BMT which makes all mtd requests made by

this commit changes the driver to check against actual chip size in chip

This patch adds a new spi-nand driver which implements the SNFI of mt7622
and mt7629.
Unlike the existing snfi driver which makes use of the spi-mem framework
and the spi-nand framework with modified ecc support, this driver is
implemented directly on the mtd framework with other components untouched,
and provides better performance, and behaves exactly the same as the nand
framework.

When adding Kernel 5.10 support, the kernel configuration did not
include the LED driver required for the UniFi 6 LR. Also the actual
driver source went missing.
