Currently ufshcd_init_host_params() sets UFS_HS_G3 as a default, so even if the device supports G4 we end up negotiating down to G3. For SoCs like gs101 which have a UFS major controller version of 3 or above advertise Gear 4. This then allows a Gear 4 link on Pixel 6. For earlier controller versions keep the current default behaviour of reporting G3.

This allows us to enable WriteBooster capability (UFSHCD_CAP_WB_EN) in a way that doesn't effect other SoCs supported in this driver. WriteBooster improves write speeds by enabling a pseudo SLC cache. Using the `fio seqwrite` test we can achieve speeds of 945MB/s with this feature enabled (until the cache is exhausted) before dropping back to ~260MB/s (which are the speeds we see without the WriteBooster feature enabled). Assuming the UFSHCD_CAP_WB_EN capability is set by the host then WriteBooster can also be enabled and disabled via sysfs so it is possible for the system to only enable it when extra write performance is required.

This leads to a significantly cooler phone when running the upstream kernel. The exynos_ufs_post_hibern8() hook is also updated to remove the UIC_CMD_DME_HIBER_EXIT code path as this causes a hang on gs101. The code path is removed rather than re-factored as no other SoC in ufs-exynos driver sets UFSHCD_CAP_HIBERN8_WITH_CLK_GATING capability. Additionally until the previous commit the hibern8 callbacks were broken anyway as they expected a bool.
