[ Upstream commit c2f30986d418f26abefc2eec90ebf06716c970d2 ]
The function _sprd_pll_recalc_rate() defines return value to unsigned
long, but it would return a negative value when malloc fail, changing
to return its parent_rate makes more sense, since if the callback
.recalc_rate() is not set, the framework returns the parent_rate as
well.

[ Upstream commit 5e75ea9c67433a065b0e8595ad3c91c7c0ca0d2d ]
The number of config registers for different pll clocks probably are not
same, so we have to use malloc, and should free the memory before return.
