[PATCH] soc: mediatek: mtk-mutex: Reduce type size for mtk_mutex_data members

All of mutex_mod and mutex_table_mod contain an array of bit
numbers, which can go from 0 to 63, it is hence not needed to
use an unsigned 32-bits integer to store that: change them to
unsigned 8-bits instead.

As for the mutex_sof table since this directly contains the values
to write to the DISP_MUTEXn_CTL register, which has only bits [13:0]
(so this register is effectively 14 bits long), change that to use
unsigned 16-bits.

The type of mutex_{mod,sof}_reg was also changed to 16 bits, as
the maximum value that those will ever have is 0x800, because it
calculates as 0x30 + (0x20 * n) where n's maximum value is 63.

This reduces module size and brings no functional changes.
