[ Upstream commit ec837d620c750c0d4996a907c8c4f7febe1bbeee ]

Fix type warnings in arch/arc/mm/cache.c.

../arch/arc/mm/cache.c: In function 'flush_anon_page':
../arch/arc/mm/cache.c:1062:55: warning: passing argument 2 of '__flush_dcache_page' makes integer from pointer without a cast [-Wint-conversion]
  __flush_dcache_page((phys_addr_t)page_address(page), page_address(page));
                                                       ^~~~~~~~~~~~~~~~~~
../arch/arc/mm/cache.c:1013:59: note: expected 'long unsigned int' but argument is of type 'void *'
 void __flush_dcache_page(phys_addr_t paddr, unsigned long vaddr)
                                             ~~~~~~~~~~~~~~^~~~~
