Subject: [PATCH] clk: mediatek: set CLK_IGNORE_UNUSED to clock mt8188 adsp audio26m

Set CLK_IGNORE_UNUSED flag to clock adsp audio26m to prevent disabling
this clock during early boot, as turning it off causes other modules
to fail probing and leads to boot failures in ARM SystemReady test cases
and the EFI boot process (on Linux Distributions, for example, debian,
openSuse, etc.). Without this flag, disabling unused clocks cannot
complete properly after adsp_audio26m is turned off.

Fixes: 0d2f2cefba64 ("clk: mediatek: Add MT8188 adsp clock support")
