ARM: renesas: Rename rmobile_get_cpu_rev_*() to renesas_get_cpu_rev_*()

Rename rmobile_get_cpu_rev_*() to renesas_get_cpu_rev_*() because
all the chips are made by Renesas, while only a subset of them is
from the R-Mobile line.

Use the following command to perform the rename:

"
$ git grep -l '\<rmobile_get_cpu_rev_\(integer\|fraction\)\>' | \
  xargs -I {} sed -i 's@\<rmobile_get_cpu_rev_\(integer\|fraction\)\>@renesas_get_cpu_rev_\1@g' {}
"
