Subject: [PATCH 2/5] mfd: sunxi-gpadc-mfd: add buffer structure
This adds a buffer structure for files including the sunxi-gpadc-mfd
header. This structure has a buffer of 32 u32 values to store data from the
FIFO of the GPADC of Allwinner SoCs. A buff_size is provided in case the
buffer is not full.
