x86/boot: Use __ALIGN_KERNEL_MASK() instead of open coded analogue 

LOAD_PHYSICAL_ADDR is calculated as an aligned (up) CONFIG_PHYSICAL_START
with the respective alignment value CONFIG_PHYSICAL_ALIGN. However,
the code is written openly while we have __ALIGN_KERNEL_MASK() macro
that does the same. This macro has nothing special, that's why
it may be used in assembler code or linker scripts (on the contrary
__ALIGN_KERNEL() may not). Do it so.
