um: Replace to_phys() and to_virt() with less generic function names

to_virt() and to_phys() are very generic and may be defined by drivers.
As it turns out, commit 9409c9b6709e ("pmem: refactor pmem_clear_poison()")
did exactly that. This results in build errors such as the following
when trying to build um:allmodconfig.

drivers/nvdimm/pmem.c: In function ‘pmem_dax_zero_page_range’:
./arch/um/include/asm/page.h:105:20: error:
			too few arguments to function ‘to_phys’
  105 | #define __pa(virt) to_phys((void *) (unsigned long) (virt))
      |                    ^~~~~~~

Use less generic function names for the um specific to_phys() and to_virt()
functions to fix the problem and to avoid similar problems in the future.
