pinctrl: renesas: Synchronize Gen2/Gen3 tables with Linux 5.2

In spite of the summary line, U-Boot commits [1-2] seem to have
aligned the U-Boot PFC tables to Linux v5.1 rather than to v5.0, since
they also imported the Linux 5.1 commits listed in [3].

What current commit tries to accomplish is to align the Gen2 and Gen3
pinctrl tables to Linux v5.2. Importing these updates in two steps
as done before (i.e. separately for Gen2 and Gen3) is somewhat difficult
due to Linux commits like [5-6] which atomically update both Gen2/3
platforms and whose breakdown would not be easily possible.

The detailed list of Linux commits squashed into this U-Boot patch is
shown in [4]. The second column in [4] depicts the patch id mismatch
between the original Linux and the resulted U-Boot commit. The
exclamation mark means that manual conflict resolution was involved
during cherry picking Linux commit into U-Boot repository (this is
mainly caused by dropped changes in files like pfc-r8a7795-es1.c and
pfc-r8a77980.c which are missing in U-Boot).

This patch has been applied on top of v2019.07-rc4-155-g8754656680b6 and
boot-tested on:
 - H3-ES2.0-Salvator-X
 - M3-ES1.1-Salvator-XS
 - M3N-ES1.1-ULCB
