ASoC: SDCA: Add bounds check for function address
SDCA 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.
