[PATCH V3 1/4] soc/tegra: pmc: Use BIT macro for register field definition

Laxman Dewangan
2016-05-04T11:52:19Z

Use BIT macro for register field definition and make constant as U
when using in shift operator like (3 << 30) to (3U << 30)

Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>

Changes from V1:
- Remove the indenting of line which is not for BIT macro usage.
Changes from V2:
- None
