[PATCH V4 2/3] soc/tegra: pmc: Correct type of variable for tegra_pmc_readl()

[Laxman Dewangan]

The function tegra_pmc_readl() returns the u32 type data and hence
change the data type of variable where this data is stored to u32
type.

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

---
Changes from V1:
-This is new in series as per discussion on V1 series to use u32 for
tegra_pmc_readl.

Changes from V2:
- Make unsigned long to u32 for some missed variable from V1.

Changes from V3:
- Revert back the value to ulong where time calcualtion is done.
