0c5605b70c mediatek: prepare old rtk switch driver for use with Linux 6.1
The old RealTek RTL8367S switch driver which is used for some MT7622
devices needs to be modified to no longer free the GPIO after reset
has completed.
This is due to Linux 5.19 removing devm_gpio_free via commit
2b038e786f83 ("gpiolib: devres: Get rid of unused devm_gpio_free()")

76198e8f09 mediatek: add led count
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.

013a956f08 mediatek: add initialization after reset
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.

84e4bbf5f0 mediatek: add support for reset gpio
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.

e9a22ce253 mediatek: cast literal value to char
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.

c4f9f9b44c mediatek: correctly log i2c response
The read response is in the i2c_response variable. Also use %hhx format,
because we're dealing with a single char.
