regmap-irq: Add driver callback to configure virtual regs
Enable drivers to configure and modify "virtual" registers, which are non-standard registers that further configure irq type on some devices. Since they are non-standard, enable drivers to configure them according to their particular idiosyncrasies by specifying an optional callback function while registering with the framework.
