Use the correct helper to update specific bitfields instead of
overwriting the entire register.

For MT7990 chipsets, critical packet mode must be enabled. Without this,
some higher priority packets may be placed in the wrong AC queue.

Align the vendor driver by adjusting the timeout values for the
MCU_UNI_CMD_EFUSE_CTRL and MCU_UNI_CMD_EXT_EEPROM_CTRL commands.
Without this adjustment, false positive command timeout errors may occur,
especially on some iPA variants.

why are you moving buf here? It is only used in the inner block.

I think we should always define and initialize buf array here, otherwise we
could use it with uninitialized values. Something like:
u8 buf[MT7996_EEPROM_BLOCK_SIZE] = {};

nit: I guess it is better to specify a different error message if rdd2_chandef

Hi Lorenzo,
The buf array is updated only if the next offset is in a different
block. For example, offsets 0x4c and 0x4d have the same block index, so
0x4d will use the same buf data read by 0x4c, instead of reading it via
MCU command again.
So we need to preserve the values in the buf array, otherwise, it will
cause undefined behavior.
Thanks,
Shayne
