The declaration of the local variable destination1 in
pm80xx_pci_mem_copy() as a pointer to a u32 results in the sparse
warning:
warning: incorrect type in assignment (different base types)
expected unsigned int [usertype]
got restricted __le32 [usertype]
Furthermore, the destination" argument of pm80xx_pci_mem_copy() is
wrongly declared with the const attribute.
Fix both problems by changing the type of the "destination" argument
to "__le32 *" and use this argument directly inside the
pm80xx_pci_mem_copy() function, thus removing the need for the
destination1 local variable.
