scsi: ufs: qcom: fix platform_msi_domain_free_irqs() reference

The newly added MSI support is mostly hidden inside of an #ifdef,
except for one line that now causes a build failure when MSI
is disabled:

drivers/ufs/host/ufs-qcom.c: In function 'ufs_qcom_remove':
drivers/ufs/host/ufs-qcom.c:1698:9: error: implicit declaration of function 'platform_msi_domain_free_irqs' [-Werror=i]
 1698 |         platform_msi_domain_free_irqs(hba->dev);
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Above that, the symbol that guards the other call was recently removed, so
that is all dead code at the moment.

Remove the incorrect #ifdef and instead of a Kconfig dependency to only
allow building the driver when CONFIG_GENERIC_MSI_IRQ is enabled. This
symbol is always present when PCI_MSI or ARM_GIC_V3_ITS are enabled, both
of which should be present on kernels that can run on Qualcomm SoCs.

The 'select RESET_CONTROLLER' in combination with this dependency
unfortunately causes a dependency loop and this is a user-visible symbol,
so it's better to change both to 'depends on'.
