ARM: OMAP3: Fix hardware detection for omap3630 when booted with device tree
SoC family definitions at the moment are reactive to board needs
as a result, beagle-xm would matchup with ti,omap3 which invokes
omap3430_init_early instead of omap3630_init_early. Obviously, this is
the wrong behavior.
With clock node dts conversion, we get the following warnings before
system hangs as a result and 3630 based platforms fails to boot
(uart4 clocks are only present in OMAP3630 and not present in
OMAP3430):
...
omap_hwmod: uart4: cannot clk_get main_clk uart4_fck
omap_hwmod: uart4: cannot _init_clocks

_enable+0x254/0x280()

So, add specific compatiblity for 3630 to allow match for Beagle-XM
platform.
