regulator: hi6421v600: Fix setting idle mode

Browse source

commit db27f8294c changed eco_mode << (ffs(sreg->eco_mode_mask) - 1)
to sreg->eco_mode_mask << (ffs(sreg->eco_mode_mask) - 1) which is wrong.
Fix it by simply set val = sreg->eco_mode_mask.

In additional, sreg->eco_mode_mask can be 0 (LDO3, LDO33, LDO34).
Return -EINVAL if idle mode is not supported when sreg->eco_mode_mask is 0.

While at it, also use unsigned int for reg_val/val which is the expected
type for regmap_read and regmap_update_bits.
