[PATCH] ARM: OMAP2: fix mailbox init code

[Ohad Ben-Cohen]

Fix this:

arch/arm/mach-omap2/mailbox.c: In function 'omap2_mbox_probe':
arch/arm/mach-omap2/mailbox.c:354: error: 'omap2_mboxes' undeclared (first use in this function)
arch/arm/mach-omap2/mailbox.c:354: error: (Each undeclared identifier is reported only once
arch/arm/mach-omap2/mailbox.c:354: error: for each function it appears in.)

Which happens on CONFIG_ARCH_OMAP2 && !CONFIG_SOC_OMAP2420, due to
missing omap2_mboxes declaration.

In addition, make sure we declare the right mailbox instances for 2430.
