atmel,osc-bypass property sets the bit 1 at main oscillator register.
On SAM9X60 this bit is not valid according to datasheet (chapter
28.16.9 PMC Clock Generator Main Oscillator Register).

Due to strobe signal not being propagated from CPU to securam
the securam needs to be mapped as device or strongly ordered memory
to work properly. Otherwise, updating to one offset may affect
the adjacent locations in securam.
