[ Upstream commit 51496e4446875726d50a5617a6e0e0dabbc2e6da ]
The pre-divider allows configuring longer PWM periods compared to using
the input clock directly. The pre-divider is 7 bit wide, meaning it's
maximum value is 128 (the register value is off-by-one: 0x7f or 127).
Change the loop to also allow for the maximum possible value to be
considered valid.

[ Upstream commit a279345807e1e0ae79567a52cfdd9d30c9174a3c ]
There is an abnormally low about 20ms,when setting duty repeatedly.
Because setting the duty will disable PWM and then enable. Delete
this operation now.

The eMMC on this board is add-on module which is not mandatory. Removing
'non-removable' property should prevent some errors when booting a board
w/o an eMMC module present.
