The emac needs constant and very specific rate but the possible PLL-sources
are very limited, so we expect the PLL source to be set manually on per
board and don't want it to get changed in an automatic way later.
So add the necessary clock-id and disable reparenting on set_rate calls.

The change fixes potential oops while accessing iomem on invalid
address, if devm_ioremap_resource() fails due to some reason.

The devm_ioremap_resource() function returns ERR_PTR() and never
returns NULL, which makes useless a following check for NULL.

Name the #define guarding compilation of this header
__RENESAS_CLK_DIV6_H__ rather than __SHMOBILE_CLK_DIV6_H__.

This is a follow-up to renaming the directory in which this file lives from
shmobile to renesas which is in turn part of an ongoing process to migrate
from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that
RENESAS seems to be a more appropriate name than SHMOBILE for the majority
of Renesas ARM based SoCs.
