Sync code to the same with tk4 pub/lts/0017-kabi, except deleted rue
and wujing. Partners can submit pull requests to this branch, and we
can pick the commits to tk4 pub/lts/0017-kabi easly.

By using CLK_OF_DECLARE_DRIVER instead of the CLK_OF_DECLARE macro, we
allow the driver to probe also as a platform driver.
While this driver does not have code to probe as a platform driver, this
is still useful for probing children devices in the case where the
device node is compatible with "simple-mfd".

The Low-Power Mode, when enabled, will make the "wait" MIPS instruction
suspend the system.
This is not really clock-related, but this bit happens to be in the
register set of the CGU.

The code was setting the bit 21 of the CPCCR register to use a divider
of 2 for the "pll half" clock, and clearing the bit to use a divider
of 1.
This is the opposite of how this register field works: a cleared bit
means that the /2 divider is used, and a set bit means that the divider
is 1.
Restore the correct behaviour using the newly introduced .div_table
field.

The main clocks (cclk, hclk, pclk, mclk, ipu) were using
incorrect dividers, and thus reported an incorrect rate.
