ARM: OMAP2/3: Define HWMOD software reset status for DMTIMERs
For OMAP2/3 devices, the HWMOD data does not define a software reset status field for the DMTIMERs. Therefore, when HWMOD performs a soft-reset of the DMTIMER we don't check and wait for the reset to complete. For OMAP2/3 devices, the software reset status for a DMTIMER can be read from bit 0 of the DMTIMER TISTAT register (referred to as the SYSS register in HWMOD). Add the appropriate HWMOD definitions so that HWMOD will check the software reset status when performing a software reset of the DMTIMER.
