Harshit Mogalapalli 40a4db8190 drm/loongson: Fix error handling in lsdc_pixel_pll_setup() ...

[ Upstream commit 5976a28b34 ]

There are two problems in lsdc_pixel_pll_setup()
1. If kzalloc() fails then call iounmap() to release the resources.
2. Both kzalloc and ioremap does not return error pointers on failure, so
   using IS_ERR_OR_NULL() checks is a bit confusing and not very right,
   fix this by changing those to NULL checks instead.
