Add clock_init_safe and clockset_pll5 functions, as these are needed for

Also add some extra clock register constant defines.

Changes in v2:
-Rebase
Changes in v3:
-Add support for all dldo and aldo-s
-Add Kconfig option to select building AXP221 and to select voltage of
 dldo and aldo-s
Changes in v4:
-Add axp221_setbits helper function
-Use symbolic names for enabled bits in CTRL1 - CTRL3 registers

The A31 uses a new push-pull two wire interface, which features higher
transfer speeds (upto 6 MHz) in theory. While the hardware can burst 8
bytes each time, this driver will only see very little use and thus is
limited to single byte transmission only.

In the current implementation of the boot sequence of UniPhier
platform, 32KB temporary RAM is available before relocation.
The malloc area and the stack shares the 32KB area.

With CONFIG_SYS_MALLOC_F_LEN set to 0x7000 (28KB), only 0x1000 (4KB)
is left for the stack.  In some use cases, the system hangs up
with stack over-flow.

Even with driver-model UART enabled, the malloc area of 0x2000 (8KB)
should be enough.

If a support card is attached to the main board, the on-board
SMSC9118 LAN controller is available.  It must be kept in reset
state for a while on start-up.

When the board is kicked via a debbuger rather than pushing the
hardware reset button, on-board chips are not reset; in this case
the reset signals should be asserted by software.

Some slow I2C devices like Power Monitor(ZM7304) at times
do not work well with low timeout value, so I2C bus get stuck
during read cycle with this device, changing it to 100ms from
10ms works fine

A lot of other i2c drivers like mxc and i2c drivers of BOOTROM
also use relax timeouts to give sufficient ticks to work well
with slower devices

ppc4xx i2c master gets stuck on errors while repeated start is
active. Can be easily reproduced by "i2c md" on an unpopulated
i2c address. There is not stop condition given, scl remains
pulled low.
The only way out seems to be doing a stop manually and then a
soft reset.

Debugging some i2c trouble I saw on my scope that repeated
start is not working properply. The 4xx even held clock pulled down
after transfers. Having a look in the driver I realized
that IIC_CNTL_RPST is set on that part of the transfer that should
begin with a repeated start. But repeated start is about not sending a
stop condition, so IIC_CNTL_RPST has to be set on the last transfer
before the repeated start happens.
