clk: amlogic: g12a: fix mmc A peripheral clock

[ Upstream commit 0079e77c08de692cb20b38e408365c830a44b1ef ]

The bit index of the peripheral clock for mmc A is wrong
This was probably not a problem for mmc A as the peripheral is likely left
enabled by the bootloader.

No issues has been reported so far but it could be a problem, most likely
some form of conflict between the ethernet and mmc A clock, breaking
ethernet on init.

Use the value provided by the documentation for mmc A before this
becomes an actual problem.
