Users of DRIVERS_UART_8250MEM_32 would have to also select
DRIVERS_UART_8250MEM to avoid missing Kconfig dependencies. Instead,
do what the OXPCIE driver dies and select the appropriate options.

This patch adds UART8250MEM_32 feature flag to support
UART8250 compatible with 32bit access in memory mapped mode.
[pg: rebuilt to reuse the existing UART8250 8bit access driver
which reduces code duplication.]

There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.
We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.
The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Squashed two related patches for splitting ARM support into general
ARM support and ARMv7 specific pieces.

This driver is only a thin shell for uart8250mem and we could extend it
with further compatible PCI IDs from other vendors/brands.

Option DRIVERS_UART builds with support for UART hardware.
Option CONSOLE_SERIAL enables the console output for UART.
Those x86 boards that do not have serial port on SuperIO should select
NO_UART_ON_SUPERIO to disable 8250 UART for the default configuration.
Removes:
CONSOLE_SERIAL_UART
HAVE_UART_IO_MAPPED
HAVE_UART_MEMORY_MAPPED
Renames:
CONSOLE_SERIAL8250 -> DRIVERS_UART_8250IO
CONSOLE_SERIAL8250MEM -> DRIVERS_UART_8250MEM

Currently this is only a minimal stub to get console on qemu-armv7.
