regmap: Add missing little endian functions
This with the longer read and write masks allow supporting more
exotic devices. For example a little endian SPI device:
static const struct regmap_config foo_regmap_config = {
.reg_bits = 16,
.reg_stride = 4,
.val_bits = 16,
.write_flag_mask = 0x8000,
.reg_format_endian = REGMAP_ENDIAN_LITTLE,
.val_format_endian = REGMAP_ENDIAN_LITTLE,
...
};
