This patch adds device tree node for the SYSREG registers block
found in Samsung S5P/Exynos SoC series. The SYSREG module
generates control signals for the ARM CPU and various IP blocks
and buses. SYSREG block registers are exposed through APB bus
interface. A sysreg device tree node is to be associated with
mfd syscon driver and all SYSREG clients should use regmap
interface it provides. It allows to eliminate any possible races
and conflicts should different drivers attempt to concurrently
access same register.

(see git commit 0cc9129d

This new location sets all of the other non-early variants
of pvops calls - and most importantly is before the

For 32-bit, CONFIG_EPAPR_PARAVIRT pulls in both epapr_paravirt.c
and epapr_hcalls.c which contains the 32-bit paravirt idle loop.

For 64-bit, the paravirt idle loop is in idle_book3e.S and that
source file is included only if CONFIG_PPC_BOOK3E_64 defined.

This patch makes that dependency for 64-bit explicit.

Fixes these build errors:
