a67bac098d MIPS: CI20: defconfig: multiple improvements
a) configure for supporting modules

Not all drivers need to be compiled into the kernel.
Support building and loading of kernel modules.

b) compile leds-gpio driver into the kernel and configure for LED triggers

DTS has been augmented to add some gpio-leds. We need the leds-gpio driver
and enable the triggers.

c) configure CONFIG_REGULATOR_ACT8865 for PMU

The PMU on the CI20 board is an ACT8600 using the ACT8865 driver.
Since it is not compiled, the PMU and the CI20 board is running in
power-on reset state of the PMU.

d) compile gpio-ir driver

The CI20 board has a gpio based IR receiver.

e) configure for CONFIG_KEYBOARD_GPIO=m

The SW1 button is hooked up to send input events.

61a47c1ad3 sysctl: Remove the sysctl system call
This system call has been deprecated almost since it was introduced, and
in a survey of the linux distributions I can no longer find any of them
that enable CONFIG_SYSCTL_SYSCALL.  The only indication that I can find
that anyone might care is that a few of the defconfigs in the kernel
enable CONFIG_SYSCTL_SYSCALL.  However this appears in only 31 of 414
defconfigs in the kernel, so I suspect this symbols presence is simply
because it is harmless to include rather than because it is necessary.

As there appear to be no users of the sysctl system call, remove the
code.  As this removes one of the few uses of the internal kernel mount
of proc I hope this allows for even more simplifications of the proc
filesystem.

MIPS: configs: Remove useless UEVENT_HELPER_PATH
Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
   CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
   made default to 'n',
2. It is not recommended (help message: "This should not be used today
   [...] creates a high system load") and was kept only for ancient
   userland,
3. Certain userland specifically requests it to be disabled (systemd
   README: "Legacy hotplug slows down the system and confuses udev").

MTD_RAW_NAND instead.

MIPS: Regenerate defconfigs
A couple of patches have come up recently to remove particular instances
of obsolete Kconfig symbols from defconfigs. Rather than doing this
piecemeal, simply regenerate them all.
