c36297b1bdSDCA only supports 3-bits for the function address, but the ACPI value is 64-bits. Update the code that parses this to do a bounds check and error out on invalid addresses. Currently, an invalid address would truncate to the bottom 3-bits when used and thus use a likely incorrect address. With the bounds check, it is also now safe to shrink the size of the adr member of sdca_function_desc to a u8 and rearrange the struct members to pack better with the new size of adr.
