[PATCH V8 1/3] soc/tegra: pmc: Use BIT macro for register field definition

[Laxman Dewangan]

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@xxxxxxxxxx>
Acked-by: Jon Hunter <jonathanh@xxxxxxxxxx>

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

Changes from V3:
- None

Changes from V4:
- Collected ack from Jon.

Changes from V5/V6:
- None

Changes from V7:
- Rebase on next-20160617
