omap: mailbox: correct OMAP4 reset logic

Browse source

OMAP4 mailbox has a different register set. There is
no MAILBOX_SYSSTATUS register. The reset is indicated
with the SOFTRESET bit of the MAILBOX_SYSCONFIG register
itself. This bit should read 0 for a successful Reset.
Also, the SOFTRESET bit occupies bit0 and not bit1 as with
previous generations.
