ARM: mm: fix type of the arm_dma_limit global variable
arm_dma_limit stores physical address of maximal address accessible by DMA,
so the phys_addr_t type makes much more sense for it instead of u32. This
patch fixes the following build warning:
arch/arm/mm/init.c:380: warning: comparison of distinct pointer types lacks a cast
