ACPI: bus: Adjust acpi_osc_handshake() parameter list

For the sake of interface cleanliness, it is better to avoid using
ACPICA data types in the parameter lists of helper functions that
don't belong to ACPICA, so adjust the parameter list of recently
introduced acpi_osc_handshake() to take a capabilities buffer pointer
and the size of the buffer (in u32 size units) as parameters directly
instead of a struct acpi_buffer pointer.

This is also somewhat more straightforward on the caller side because
they won't need to create struct acpi_buffer objects themselves to pass
them to the helper function and it guarantees that the size of the
buffer in bytes will always be a multiple of 4 (the size of u32).

Moreover, it addresses a premature cap pointer dereference and
eliminates a sizeof(32) that should have been sizeof(u32) [1].
