The pins from GPIO2B0 to GPIO2B6 are located at GRF_GPIO2BL_IOMUX,
they are recalculated to get correct iomux.

The usage of slew rate is needed to config it at DTS,
such as:
fast speed: slew-rate = <1>;

If the gpio IRQ type changes, it is possible to accidentally trigger
an interrupt, such as when the input is high, changed from level to
rise edge. For now, the best way to do this is to disable the INTEN
bit first, then configure the type to stagger this period of time.

There are writable 32 bits for PMU_GPIO0's iomux, so add the
IOMUX_WRITABLE_32BIT to read iomux register at first, it would
not change others' bits.

The interrupt is requested before the device is powered on and
it's value in some cases cannot be reliable. It happens on some
devices that an interrupt is generated as soon as requested
before having the chance to disable the irq.

we only add the property of regulator and clock to cpu0 and cpu4 node,
but if cpu4~cpu7 is down and then we up cpu5~cpu7, they will can not
get their regulator and clock. So we should add the properties to all
cpu node.

The gc2145 always rewrite init setting,
when change state from preview to capture.
That will get exposure time again when capture picture,
it causes capture exposure time different with preview.
To fix this issue, following changes introduced:
- reconfig gc2145 reg_table.
- add gc2145_aec_ctrl function calculate Capture shutter.

Now a regulator device can supply multiple consumers at the same time,
if a consumer starts and set a low voltage, another consumer doesn't
start in kernel but has been set a high frequency in bootloader will
abort.
This patch Adds support to limit min_uV during kernel startup to make
sure the voltage can suit the needs of all consumers.
