LoongArch: Consolidate early_ioremap()/ioremap_prot()
1. Use phys_addr_t instead of u64, which can work for both 32/64 bits.
2. Check whether the input physical address is above TO_PHYS_MASK (and
return NULL if yes) for the DMW version.
Note: In theory early_ioremap() also need the TO_PHYS_MASK checking, but
the UEFI BIOS pass some DMW virtual addresses.
