in 3630 TRM, There is a hole in the memory map between
0x48002264(CONTROL_PADCONF_SDRC_CKE1) and
0x480025A0(CONTROL_PADCONF_SDRC_BA0) which obviously generates abort
when read at 0x48002268

on 3430, we should also see a crash in the hole region
0x48002264(CONTROL_PADCONF_SDRC_CKE1) to
0x480025D8(CONTROL_PADCONF_ETK_CLK).

in dts, omap3_pmx_core: pinmux@48002030 describes the range as reg =
<0x48002030 0x05cc> (which is the max range for the module)

wish pinctrl-single driver could support handle multiple address ranges?
