[PATCH] ARM: shmobile: R-Mobile: Remove !CONFIG_PM_RUNTIME section

[Geert Uytterhoeven]

As of commit b2b49ccbdd547135 ("PM: Kconfig: Set PM_RUNTIME if PM_SLEEP
is selected"), CONFIG_PM_RUNTIME is always enabled if CONFIG_PM is
enabled, so this section is no longer needed.

As of commit 464ed18ebdb6236f ("PM: Eliminate CONFIG_PM_RUNTIME"),
CONFIG_PM_RUNTIME no longer exists, and this section will always be
executed, which may enable clocks that are not needed.

This reverts commit 64b0089e0c486736 ("ARM: shmobile: R-Mobile: Enable
module clocks if !CONFIG_PM_RUNTIME").

On r8a7740/armadillo, without this patch the MSTP clocks for CEU20, FSI,
IIC[01], LCDC1, SCIFA[02-7], SCIFB, SY_DMAC[1-3], TPU0, and USB_DMAC are kept
running.
