[ Upstream commit 75eccf5ed83250c0aeaeeb76f7288254ac0a87b4 ]

According to the datasheet, in Meson-GXBB/GXL series,
The clock gate bit for SARADC is HHI_GCLK_MPEG2 bit[22],
while clock gate bit for SANA is HHI_GCLK_MPEG0 bit[10].

Test passed at gxl-s905x-p212 board.

The following published datasheets are wrong and should be updated
[1] GXBB v1.1.4
[2] GXL v0.3_20170314
