[PATCH] ARM: OMAP: hwmod: Fix error handling in functions used OMAP4 onwards

[rnayak@ti.com (Rajendra Nayak)]

Some functions like _omap4_disable_module() and _omap4_wait_target_disable()
are (will be) used on all OMAPs OMAP4 and beyond which support module level
control. Fix the error checks in these functions to return if called on
any platform pre OMAP4 (i.e OMAP2 and OMAP3) instead of checking for
!cpu_is_omap44xx(). This avoids having to update the error check with a
'&& !cpu_is_omap54xx()' when OMAP5 is introduced and possibly similar updates
when further OMAP generations are added.
