clk: mediatek: drop two dead config options

Commit 0f471d31 ("clk: mediatek: Split MT8195 clock drivers and allow
module build") adds a number of new COMMON_CLK_MT8195_* config options.
Among those, the config options COMMON_CLK_MT8195_AUDSYS and
COMMON_CLK_MT8195_MSDC have no reference in the source tree and are not
used in the Makefile to include a specific file.

Drop the dead config options COMMON_CLK_MT8195_AUDSYS and
COMMON_CLK_MT8195_MSDC.
