Suggested by Marek, continuation of cleanup of PMU register defines
in headers.

Let's keep all of them in include/linux/soc/samsung/exynos-regs-pmu.h.

Merging strategy: probably through phy tree (in that case they have
samsung-soc's ack).
I can also take it through samsung-soc - please let me know.


Changes since v1:
=================
1. Rebase - dependencies should be already in.
2. Add Lee's acks.



Best regards,
Krzysztof

Phy drivers access PMU region through regmap provided by exynos-pmu
driver.   However there is no need to duplicate defines for PMU
registers.  Instead just use whatever is defined in exynos-regs-pmu.h.

Additionally MIPI PHY registers for Exynos5433 start from the same
address as Exynos4 and Exynos5250 so re-use existing defines.

This reduces number of defines and allows removal of one header file.

Right, I will leave only the first part about number of defines.

Exynos4 MIPI phy registers are defined with macro calculating the offset
for given phyN.  Use the same method for Exynos5420 to be consistent.

There is no need for separate defines for Exynos4 and Exynos5 phy enable
bit and MIPI phy reset bits.  In both cases there are the same so
simplify it.

This reduces number of defines and allows removal of one header file.

EXYNOS5433_PAD_INITIATE_WAKEUP_FROM_LOWPWR is not defined in
<soc/samsung/exynos-regs-pmu.h> and is still used by
drivers/mfd/exynos-lpass.c (at least in next-20170310)

Do I miss something or it needs to be fixed?

Yeah, kbuild also told me that. :)

I fixed it in v3, can you take a look?
