powerpc/8xx: Force VIRT_IMMR_BASE to be a positive number
The asm-offsets mechanism generates signed numbers, even if the
input value is explicitly unsigned. This causes a problem with
older binutils (e.g. 2.23), which sign-extend a negative number
when @h is applied. Thus, this instruction:
cmpli cr0, r11, VIRT_IMMR_BASE@h
resulted in this:
Error: operand out of range (0xfffffff0 is not between 0x00000000 and
0x0000ffff)
By casting to a larger type, we can force the output to be expressed
as a positive number.
