Subject: [PATCH 0/7] UFS cleanups and enhancements to ufs-exynos for gs101

Hi folks,

This series provides a few cleanups, bug fixes and feature enhancements for
the ufs-exynos driver, particularly for gs101 SoC.

Regarding cleanup we remove some unused phy attribute data that isn't
required when EXYNOS_UFS_OPT_SKIP_CONFIG_PHY_ATTR is not set.

Regarding bug fixes the check for EXYNOS_UFS_OPT_UFSPR_SECURE is moved
inside exynos_ufs_config_smu() which fixes a serror in the resume path
for gs101.

Regarding feature enhancements:
* Gear 4 is enabled which has higher speeds and better power management
* WriteBooster capability is enabled for gs101 which increases write
  performance

Note further patches in a separate series will follow to enable
UFSHCD_CAP_HIBERN8_WITH_CLK_GATING once the phy hibern8 interface is
settled over in [1]
