It appears that Gen2 is a misnomer for the R-Car PCIE driver
which also supports Gen 1 and Gen 3 SoCs. Accordingly, drop Gen 2
from the help text and Kconfig symbol.
Also, re-arange the Kconfig symbol name to use PCIE as the prefix.
This appears to be in keeping with other PCIE Kconfig symbols.

Hi Geert,
testing 4.6-rc5 on a custom R-Car H3 board, I noticed that the Linux
console attached to SCIF2 no longer works (it works on 4.5). earlycon
works fine, though. Unlike Salvator-X, this H3 board does not use an
external SCIF clock and thus, scif_clk is not enabled in the board
device tree.
