msm: camera: csiphy: Remove dynamic memory alloc for csiphy reg info

Currently during csiphy component bind, we are allocating memory for
csiphy register info structure, which is not required, since the
structure in statically defined in headers. This causes panic during
unbind calls, since we are supplying address to statically allocated
memory that we previously pointed to, during bind. Remove dynamic
memory alloc and free to fix this issue.
