x86-32: Fix sparse warning for the __PHYSICAL_MASK calculation
On 32-bit non-PAE system, cast to 'phys_addr_t' truncates value
before subtraction. Subtracting before cast produce same result
but remove following warnings from sparse:
arch/x86/include/asm/pgtable_types.h:255:38: warning: cast truncates bits from constant value (100000000 becomes 0)
arch/x86/include/asm/pgtable_types.h:270:38: warning: cast truncates bits from constant value (100000000 becomes 0)
arch/x86/include/asm/pgtable.h:127:32: warning: cast truncates bits from constant value (100000000 becomes 0)
arch/x86/include/asm/pgtable.h:132:32: warning: cast truncates bits from constant value (100000000 becomes 0)
arch/x86/include/asm/pgtable.h:344:31: warning: cast truncates bits from constant value (100000000 becomes 0)
64-bit or PAE machines will not be affected by this change.
