This patch adds support for the Global Clock Controller on QCom SM4250 and
SM6115, codename bengal. The code is taken from OnePlus repo [1]. The two
platforms are identical so there is only one compat string.

[1]: https://github.com/OnePlusOSS/android_kernel_oneplus_sm4250

v1: https://lkml.org/lkml/2021/6/22/1131
v2: https://lkml.org/lkml/2021/6/27/157
v3: https://lkml.org/lkml/2021/8/1/68

Changes from v3:
- removed test clock from driver/binding
- fix GCC_SDCC2_BCR value as spotted by Konrad
- simplified probe function

Changes from v2:
- Suggested by Stephen Boyd
  - switch to parent_data in place of parent_names
- other
  - drop parent refs to invalid clocks
  - use pll-alpha regs when possible
  - drop unused parent defs
  - add pll test clock to bindings

Changes from v1:
- remove sm4250 compat, there will be a single sm6115.dtsi for both platforms
