The voltage setting code knows it needs to call axp221_init before calling
the various voltage setting functions.

But users of axp utility functions like axp221_get_sid() do not know this,
so the utility functions always call axp221_init() to ensure that the
p2wi / rsb setup magic has been done.

Since doing this repeatedly is quite expensive, add a check to axp221_init
so that it only does the initialization once.

Currently the pre-console buffer can accumulate early log messages
and flush them to the serial console as soon as it becomes available.

This patch just adds one more pre-console buffer flushing point and
does all the same for the other consoles too. This is particularly
useful for the vga/hdmi/lcd console, where we can see all the older
messages now (except for the log messages from SPL).

Naturally, we don't want to get an extra copy of the log messages
on the serial console again at the second flushing point, so the
serial console has to be explicitly filtered out.

Based on the original version by Marc Zyngier. It adds a psci_cpu_off
implementation for the A20 SoC. The mechanism works by first preparing
the calling CPU to go offline (disable and flush cache, disable SMP),
then requesting CPU 0 to pull the plug. The request is sent as FIQ on
SGI15.

In some extreme cases it may be necessary to wait 1.5 seconds or more for a hpd
signal to show up (and be able to read edid info), but we do not want to
penalize all headless boots with an extra second boot delay, so add a hpd_delay

Some boards use GPIO-s on the pmic, one example of this is the A13-OLinuXino
board, which uses gpio0 of the axp209 for the lcd-power signal.

This commit adds support for gpio pins on the AXP209 pmic, the sunxi_gpio.c
changes are universal, adding gpio support for the other AXP pmics (when
necessary) should be a matter of adding the necessary axp_gpio_foo functions
to their resp. drivers, and add "#define AXP_GPIO" to their header file.

Note this commit only adds support for the non device-model version of the
gpio code, patches for adding support to the device-model version are very
welcome.

The string representation for these gpio-s is AXP0-#, the 0 in the AXP0 prefix
is there in case we need to support gpio-s on more then 1 pmic in the future.
At least A80 boards have 2 pmics, and we may end up needing to support gpio-s
on both.

Add a write to the "unknown" (*) register to enable auto input sync, when
initially adding sunxi hdmi output support this magic write from the android
kernel code was missed, causing lcdc -> hdmi encoder sync problems.

With this write added, we can drop the modesetting retries and the extra
delays added to work around these sync problems.

With the retries dropped there also is no need to 0 all the enable flags at
the beginning of the modeset, as they are initialized to 0 already by
engines_init.
