ACPI atomicio: Convert width in bits to bytes in __acpi_ioremap_fast()

Browse Source 
commit 3bf3f8b19d upstream.

Callers to __acpi_ioremap_fast() pass the bit_width that they found in the
acpi_generic_address structure. Convert from bits to bytes when passing to
__acpi_find_iomap() - as it wants to see bytes, not bits.
