ACPICA: Revert "Fix for implicit result conversion for the To____ functions"

ACPICA commit 0e44fee13434766ebbb4d156e3ed45604508d7c3

This reverts commit e1342c9f2dde37a67e916099658b65984ef8a434.
Implicit conversion should in fact be disabled for the "explicit
conversion" operators. This is stated in the ACPI specification.
The operators affected are:
to_integer
to_string
to_buffer
to_decimal_string
to_hex_string
to_BCD
from_BCD
