T7870: Kernel add option CONFIG_NO_HZ_FULL

Add options CONFIG_NO_HZ_FULL and CONFIG_RCU_NOCB_CPU for:
 - system option kernel cpu nohz-full
 - system option kernel cpu rcu-no-cbs

Fixes:
```
kernel: Housekeeping: nohz unsupported. Build with CONFIG_NO_HZ_FULL
r14 kernel: Unknown kernel command line parameters
```
