Subject: [RESEND PATCHv1 0/8] mmc: sdhci-msm: Provide support for enhanced strobe

Hi, 

Resending this patch series, as no one could review it -possibly due to
holidays during that time.

This patch series mainly provides enhanced strobe support to sdhci-msm driver
along with some additions of HW recommended sequence. This has been tested on
8996 based internal target & on db410c.

Patches 1-3 :- Factors out few functions to be re-used again.
	       To also simplify large functions and makes it more readable.

Patches 4-5 :- Few recommendations based on HW prog. guide.

Patches 6 :- Clear SDHCI_HS400_TUNING flag after platform_execute_tuning
	     so that ->platform_execute_tuning (underlying platform driver) can
	     know about HS400 tuning.

Patch 7 :- Implements an additional step as per HPG for HS400 tuning.

Patch 8 :- Implements enhanced strobe functionality in sdhci-msm driver.
