Mark function of_reset_simple_xlate() as static in core.c
because it is not used outside this file.
Also, remove functions devm_reset_control_put() and
devm_reset_control_match() because they are unused.
This eliminates the following warnings in core.c:
drivers/reset/core.c:46:5: warning: no previous prototype for ‘of_reset_simple_xlate’ [-Wmissing-prototypes]
drivers/reset/core.c:262:6: warning: no previous prototype for ‘devm_reset_control_put’ [-Wmissing-prototypes]

If the requested reset controller is not yet available, have reset_control_get
and device_reset return -EPROBE_DEFER so the driver can decide to request
probe deferral.

The Allwinner A31 and most of the other Allwinner SoCs have an IP
maintaining a few other IPs in the SoC in reset by default. Among these
IPs are the A31's High Speed Timers, hence why we can't use the regular
driver construct in every cases, and need to call the registering
function directly during machine initialisation.
Apart from this, the implementation is fairly straightforward, and could
easily be moved to a generic MMIO-based reset controller driver if the
need ever arise.

"rstc" is NULL here and we should use "rcdev" instead of "rstc->rcdev".

This adds a simple API for devices to request being reset
by separate reset controller hardware and implements the
reset signal device tree binding.
