Subject: [RFC v2 00/12] Misc patches for QCOM clocks

* v2:

1. Discussion is going on with HW team to fix the offset issue in next chip
   version so removed the RCG patch
2. Made “fix 16 bit alpha support calculation” generic to support all cases.

3. Clubbed the [1] and Patch [2] for "support for dynamic updating the PLL"
   a. The PLL_LATCH_INTERFACE bit is not available in every Alpha PLL and it
      will be turned off after default power on. If the PLL user want to turn
      off the LATCH_INTERFACE then they can directly set this bit in
      PLL_USER_CTL_U during alpha_pll_configure and clear the dynamic update
      flag bit
   b. The latching procedure is only required if PLL is enabled
   c. The handling is different according to PLL_UPDATE_BYPASS bit

4. Added the patch for “2 bit PLL post divider”
