[PATCH v2 6/6] x86: move CONFIG_PHYS_ADDR_T_64BIT setting into Kconfig

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

sizeof(phys_addr_t) depends on whether CONFIG_PHYS_ADDR_T_64BIT is
enabled, which we so far defined depending on __x86_64__ in a header
file.

Given that we have a 64BIT symbol already in Kconfig that's selected
when building for 64-bit, let's have it select PHYS_ADDR_T_64BIT.

v1 -> v2:
  - drop CONFIG_PHYS_ADDR_T_64BIT assignment in header file
  - reword commit message accordingly
