irqchip/mips-gic: Allow forced affinity

Devices of the Realtek MIPS Otto platform use the official rtl-otto-timer
as clock event generator and CPU clocksource. It is registered for each CPU
startup via cpuhp_setup_state() and forces the affinity of the clockevent
interrupts to the appropriate CPU via irq_force_affinity().

On the "smaller" devices with a vendor specific interrupt controller
(supported by irq-realtek-rtl) the registration works fine. The "larger"
RTL931x series is based on a MIPS interAptiv dual core with a MIPS GIC
controller. Interrupt routing setup is cancelled because gic_set_affinity()
does not accept the current (not yet online) CPU as a target.

Relax the checks by evaluating the force parameter that is provided for
exactly this purpose like in other drivers. With this the affinity can be
set as follows:

 - force = false: allow to set affinity to any online cpu
 - force = true:  allow to set affinity to any cpu
