Joel Fernandes 912e663127 ARM: OMAP2+: Disable POSTED mode for errata i103 and i767 
Enabling of Posted mode is seen to cause problems on dmtimer modules on AM33xx
(much like other OMAPs).  Reference discussions on forums [1] [2]. Earlier
patch solving this on other OMAPs [3].

For OMAP SoCs with this errata, the fix has been to not enable Posted mode.
However, on some SoCs (atleast AM33xx) which carry this errata, Posted mode
is enabled on reset. So we not only need to ignore enabling of the POSTED bit
when the timer is requested, but also disable Posted mode if errata is present.
