To make the names proper and more appropriate:
Rename the driver name from tps65090-regulator to tps65090-pmic.
Rename the regulators from TPS65090_ID_* to TPS65090_REGULATOR_*

TPS65090 supports the two LDOs, LDO1 and LDO2. These are
always ON regulators. The output on these LDOs are available
once the input voltage available for these LDOs.
Add support for these LDOs regulators.

We will not able to register regulator if there is no ops.
