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

Browse Source 
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.

After any reset, the boot ROM searches the boot media for a valid
boot image. For non-XIP devices, the ROM then copies the image into
internal memory. For all boot modes, after the ROM processes the
boot image it eventually computes the entry point address depending
on the device type (secure/non-secure), boot media (xip/non-xip) and
