ARM: mach-omap2: Kconfig: Allow OMAP5 devices to set entry point

Like AM33xx and AM43xx, DRA7xx and AM57xx devices may need to
have an non-standard boot address in memory. This may be due
to the device being a high security variant, which place the
Initial SoftWare (ISW) after certificates and secure software.

Allow these devices to set this from Kconfig.
