qe_lib: Remove immrbar_virt_to_phys() function

Remove private address mapping function immrbar_virt_to_phys() as it can be replaced by kernel generic API like iopa(). iopa() had problem dealing with area mapped by io_block_mapping(). It's now working as all io spaces are mapped by ioremap(). Users of this function should change to use generic functions.
