ARM: dts: imx51: Add aipstz nodes
Currently when trying to use the 'devmem' tool to read/write
registers the following bus error is observed:
[ 82.689185] Unhandled fault: external abort on non-linefetch (0x1018) at 0xb6ff10c4
[ 82.697071] pgd = (ptrval)
[ 82.699920] [b6ff10c4] *pgd=a87c5831, *pte=73fa8383, *ppte=73fa8a33
Bus error
Add the aipstz nodes, so that the following function from
imx51_dt_init() can work properly:
imx_aips_allow_unprivileged_access("fsl,imx51-aipstz");
After adding these nodes, 'devmem' tool can work correctly,
which is very useful for debugging purposes.
