[PATCH v4 3/4] ARM: OMAP2: MUSB: Specify omap4 has mailbox

[Kishon Vijay Abraham I <kishon-l0cyMroinI0@public.gmane.org>]

Added has_mailbox to the musb platform data to specify that omap uses
an external mailbox (in control module) to communicate with the musb
core during device connect and disconnect.
