drivers: interrupt_controller: intc_clic: add CLIC parameters

Browse source 
Add support for CLIC hardware parameters based on the hardware
implementation.

  1. CLIC_PARAMETER_INTCTLBITS
    Specifies the number of modifiable bit in interrupt control register.

  2. CLIC_PARAMETER_MNLBITS
    Specifies the number of bits are assigned to interrupt level in the
    interrupt control bits.

This option specifies the number of modifiable bits in the clicintctl
registers.
