Convert some MIPS architecture's code to using struct syscore_ops
objects for power management instead of sysdev classes and sysdevs.
This simplifies the code and reduces the kernel's memory footprint.
It also is necessary for removing sysdevs from the kernel entirely in
the future.

Assume that the boot loader knows the physical memory of the system and
deduce that information from the contents of the SDRAM control register.
It is still possible to override with with the "mem=" parameter, but we
have a sensible default now.

The code for supporting one-shot mode for the clockevent is already there,
only the feature flag was not set. Setting the one-shot flag allows the
kernel to run in tickless mode.

The conversion did not make use of the new chip flag which signals the
core code to mask the chip before calling the set_type callback. Sigh.
Use the new lockdep helper as well.

Currently there is one irq_chip per gpio_chip with the only difference
being the name. Since the information whether the irq belong to GPIO
bank A, B, C or D is not that important rewrite the code to simply use
a single irq_chip for all gpio_chips.

Needed to update to apply fixes for which the old branch was too
outdated.
This patch fixes the following section mismatch:
WARNING: arch/mips/built-in.o(.text+0xc): Section mismatch in reference from the

While at it, fix two checkpatch errors.
Several non-const struct instances constified by this patch were added after
the introduction of platform_suspend_ops in checkpatch.pl's list of "should
be const" structs (79404849e9).
Patch against mainline.
Inspired by hunks of the grsecurity patch, updated for newer kernels.

The JZ4740 UART interface is almost 16550 compatible.
The UART module needs to be enabled by setting a bit in the FCR register
and it has support for receive timeout interrupts. Instead of adding yet
another machine specific quirk to the 8250 serial driver we provide a
serial_out implementation which sets the required additional flags.
