serial: rp2: New driver for Comtrol RocketPort 2 cards

Browse Source 
This driver supports the RocketPort EXPRESS and RocketPort INFINITY
families of PCI/PCIe multiport serial adapters.  These adapters use a
"RocketPort 2" ASIC that is not compatible with the original RocketPort
driver (CONFIG_ROCKETPORT).

Tested with the RocketPort EXPRESS Octa DB9 and Quad DB9.  Also added an
old RocketPort 8J PCI card to the same system to verify that rocket.c and
rp2.c coexist peacefully.

This driver supports the Comtrol RocketPort EXPRESS and
RocketPort INFINITY families of PCI/PCIe multiport serial adapters.
These adapters use a "RocketPort 2" ASIC that is not compatible
with the original RocketPort driver (CONFIG_ROCKETPORT).
To compile this driver as a module, choose M here: the
module will be called rp2.
If you want to compile this driver into the kernel, say Y here. If
you don't have a suitable RocketPort card installed, say N.

If multiple cards are present, the default limit of 32 ports may
need to be increased.
