ACPI atomicio: Convert width in bits to bytes in __acpi_ioremap_fast()
commit 3bf3f8b19d2bfccc40f13c456bf339fd8f535ebc 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.
