[PATCH v2 1/2] regulator: pca9450: Use LDO5 low-control enable mask

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@nabladev.com>

LDO5 has voltage-selection fields in both LDO5CTRL_L and LDO5CTRL_H,
selected by the SD_VSEL pin. Its ENMODE field, however, is only in
LDO5CTRL_L.

The regulator descriptors correctly use LDO5CTRL_L as enable_reg, but
use the misleading LDO5H_EN_MASK name for enable_mask. Both mask
definitions have the same value, so this causes no functional problem.

Use LDO5L_EN_MASK in all LDO5 descriptors and remove the unused
LDO5H_EN_MASK definition.

Changes since v1:
- New patch clarifying that the LDO5 ENMODE field is in LDO5CTRL_L.
