irqchip/ts4800: Convert to platform_driver::remove_new() callback The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

irqchip: Bulk conversion to generic_handle_domain_irq() Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq().

irqchip/ts4800: Make ts4800_ic_ops static const ts4800_ic_ops is only referenced in this driver, so make it static. In additional, it's never get modified thus also make it const.

irqchip/ts4800: Add TS-4800 interrupt controller This commit adds support for the TS-4800 interrupt controller. This controller is instantiated in a companion FPGA, and multiplex interrupts for other FPGA IPs. As this component is external to the SoC, the SoC might need to reserve pins, so this controller is implemented as a platform driver and doesn't use the IRQCHIP_DECLARE construct.
