Subject: [PATCH v2 1/2] irqchip/irq-msi-lib: Select CONFIG_GENERIC_MSI_IRQ

irq-msi-lib directly uses struct msi_domain_info and
MSI_FLAG_ALLOC_SIMPLE_MSI_DESCS (and likely more) which are only available
when CONFIG_GENERIC_MSI_IRQ=y.

However, no dependency is specified. If it happens that
CONFIG_IRQ_MSI_LIB=y while CONFIG_GENERIC_MSI_IRQ=n, the kernel fails to
build.

Specify this dependency and fix the build.

Fixes: 72e257c6f058 ("irqchip: Provide irq-msi-lib")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202506282256.cHlEHrdc-lkp@intel.com/
