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]
