ARM: renesas: Rename RMOBILE_CPU_TYPE_* to RENESAS_CPU_TYPE_*

Rename RMOBILE_CPU_TYPE_* to RENESAS_CPU_TYPE_* 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_CPU_TYPE_[A-Z0-9]\+\>' | \
  xargs -I {} sed -i 's@\<RMOBILE\(_CPU_TYPE_[A-Z0-9]\+\)\>@RENESAS\1@g' {}
"
