MIPS: Fix build error due to multiple prom_putchar() definitions.

This can happen if both the generic 8250 and another early console
driver are enable.  Fixed by using an auxilliary kconfig symbol to
restrict that choice.

MIPS: Alchemy: remove duplicate UART register offset definitions

The UART register names are identical to the ones in uapi/linux/serial_reg.h,
which causes build failures in various drivers when they indirectly pull in
the au1000.h header, for example via gpio.h:

In file included from arch/mips/include/asm/mach-au1x00/gpio.h:13:0,
                 from arch/mips/include/asm/gpio.h:4,
                 from include/linux/gpio.h:48,
                 from include/linux/ssb/ssb.h:9,
                 from drivers/ssb/driver_mipscore.c:11:
arch/mips/include/asm/mach-au1x00/au1000.h:1171:0: note: this is the location of the previous definition
 #define UART_LSR 0x1C /* Line Status Register */

Get rid of the altogether, nothing in the core Alchemy code depends
on them any more.

MIPS: Hibernate: Flush TLB entries in swsusp_arch_resume()

The original MIPS hibernate code flushes cache and TLB entries in
swsusp_arch_resume(). But they are removed in Commit 44eeab67416711
(MIPS: Hibernation: Remove SMP TLB and cacheflushing code.). A cross-
CPU flush is surely unnecessary because all but the local CPU have
already been disabled. But a local flush (at least the TLB flush) is
needed. When we do hibernation on Loongson-3 with an E1000E NIC, it is
very easy to produce a kernel panic (kernel page fault, or unaligned
access). The root cause is E1000E driver use vzalloc_node() to allocate
pages, the stale TLB entries of the booting kernel will be misused by
the resumed target kernel.

irqchip: sun7i/sun6i: Disable NMI before registering the handler

It is advisable to disable the NMI before registering the IRQ handler as
registering the IRQ handler unmasks the IRQ on the GIC, so if U-Boot has
left the NMI enabled and the NMI pin is active we will immediately get
an interrupt before any driver has claimed the downstream interrupt of
the NMI.
