Jerome Brunet 795c633f60 mmc: meson-gx: fix __ffsdi2 undefined on arm32 ...

Using __bf_shf does not compile on arm 32 architecture.
This has gone unnoticed till now cause the driver is only used on arm64.

In addition, __bf_shf was already used in the driver without any issue.
It was used on a constant value, so the call was probably optimized
away.

Replace __bf_shf by __ffs fixes the problem
