ARM: OMAP2+: Drop legacy platform data for omap4 gpu

Browse Source 
I've tested that the interconnect target module enables and idles
just fine when probed with ti-sysc with PM runtime control via sys:

# echo on > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
0x56000024 = 0x00010200		# SGX540 CORE_REVISION
# echo auto > $(find /sys -name control | grep \/5601)
# rwmem 0x56000024
And when idled, it will produce "Bus error" as expected.
