[PATCH v3 02/11] ALSA: firewire-lib/motu: use int type for the value of bitwise OR with enumerator-constant

[Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>]

It brings some inconvenience in practice to use enumerated type for
variable to which bitwise OR with enumerator constant is assigned.

This commit replaces declarations of enumerated type with int type.
