by moving CONSOLE_UART_BASE_ADDRESS back to the SoC-specific code, since

contained those base addresses, so remove that as well.

The UARTs in the Picasso SoC are memory mapped, but there is also some
hardware support that isn't used by any board to make the UARTs behave
like the ones found on legacy x86 machines from the 90s.
In the MMIO mode the MMIO address of the UART controller is passed to
the OS via ACPI. The OS expects the base clock of the UART controller to
be 48MHz (see the cz_uart_desc struct in drivers/acpi/acpi_apd.c and
drivers/tty/serial/8250/8250_dw.c in the Linux kernel) in this case. It
is also possible to enable additional decodes from four 8 byte legacy
I/O locations used for serial ports to the different UART controllers,
which doesn't disable the MMIO access though. The legacy I/O-mapped
serial ports are usually expected to have a base clock of 16*115200Hz
which the hardware can also provide to the UART's baud rate generator.
So there are two possible valid configurations to use the UARTs; either
MMIO access in combination with a 48MHz base clock or the legacy I/O
decode with a ~1.8MHz base clock.
The existing code unconditionally generates ACPI objects for all enabled
UARTs, so those shouldn't be put into legacy mode and switching the base
clock to ~1.8MHz was only done in the case that the UART was used as
coreboot console UART which still used the MMIO access, but the lower
base clock. Since no board even selects this option and it's rather
invasive to properly implement this feature, just drop the corresponding
broken code.
TEST=SoC UART console still works on Mandolin.

The S3/S4 workaround is specific to Panther Point stepping A0, and it is
wrongly implemented. Rewrite the whole function as per reference code.
Since this runs in SMM, be overly cautious and double-check everything.
Do not rely on GNVS to determine if xHCI is enabled. Instead, check
whether the corresponding bit in the Function Disable register is set.
Only Panther Point has xHCI, so exit early if this is not the case.
