mfd: as3722: Make FUSE7_REG readable
The FUSE7_REG register is not currently marked readable. This causes as3722_sd0_is_low_voltage() to emit an error during boot, and assume the range of the SD0 regulator: as3722-regulator as3722-regulator: Reg 0xa7 read failed: -5 Fixes: d4807ad2c4c0 ("regmap: Check readable regs in _regmap_read") [exposed the bug, by checking for readability] Fixes: 762a8ee80897 ("regulator: as3722: detect SD0 low-voltage mode") [left out this register from the readable list] Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
