When RESET_CONTROLLER is not set, kconfig complains about missing
dependencies for RESET_TI_SYSCON, so add the missing dependency just as is
done above for SCSI_UFS_QCOM.
Silences this kconfig warning:
WARNING: unmet direct dependencies detected for RESET_TI_SYSCON
Depends on [n]: RESET_CONTROLLER [=n] && HAS_IOMEM [=y]
Selected by [m]:
- SCSI_UFS_MEDIATEK [=m] && SCSI_UFSHCD [=y] && SCSI_UFSHCD_PLATFORM [=y] && ARCH_MEDIATEK [=y]

Now that there is a new dedicated ICE driver, drop the ufs-qcom-ice and use
the new ICE api provided by the Qualcomm soc driver ice. The platforms that
already have ICE support will use the API as library since there will not
be a devicetree node, but instead they have reg range. In this case, the
of_qcom_ice_get will return an ICE instance created for the consumer's
device. But if there are platforms that do not have ice reg in the consumer
devicetree node and instead provide a dedicated ICE devicetree node, the
of_qcom_ice_get will look up the device based on qcom,ice property and will
get the ICE instance registered by the probe function of the ice driver.
The ICE clock is now handle by the new driver. This is done by enabling it
on the creation of the ICE instance and then enabling/disabling it on UFS
runtime resume/suspend.

The TC G210 driver only supports devices declared in the device tree.
Hence make this driver dependent on CONFIG_OF. This patch fixes the
following compiler error:
drivers/ufs/host/tc-dwc-g210-pltfrm.c:36:34: error: ‘tc_dwc_g210_pltfm_match’ defined but not used [-Werror=unused-const-variable=]

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'.

Modify the UFSHCD core to allow 'struct ufshcd_sg_entry' to be
variable-length. The default is the standard length, but variants can
override ufs_hba::sg_entry_size with a larger value if there are
vendor-specific fields following the standard ones.
This is needed to support inline encryption with ufs-exynos (FMP).

Split the drivers/scsi/ufs directory into 'core' and 'host' directories
under the drivers/ufs/ directory. Move shared header files into the
include/ufs/ directory. This separation makes it clear which header files
UFS drivers are allowed to include (include/ufs/*.h) and which header files
UFS drivers are not allowed to include (drivers/ufs/core/*.h).
Update the MAINTAINERS file. Add myself as a UFS reviewer.
