[PATCH 1/6] ARM: STi: DT: STiH407: Fix retime pin mask for PIO5 and PIO35

From: Karim BEN BELGACEM <karim.ben-belgacem at st.com>

This will avoid programming the retime registers when not implemented

- PIO5  : no retime registers assigned to pins 6 and 7
- PIO35 : pin 7 is reserved so no retime register assigned to it
