This series implements EDAC driver for QCOM SoCs. As of now, this driver
supports EDAC for Last Level Cache Controller (LLCC). LLCC EDAC driver is
to detect and report single and double bit errors on Last Level Cache
Controller (LLCC) cache. This driver also takes care of dumping registers
and also adding config options to enable and disable panic when these
errors happen in LLCC.

The driver functionality is implemented in:
qcom_edac.c : This platform driver registers to edac framework and
handles the single and double bit errors in cache by registering
interrupt handlers.

llcc-slice.c: It invokes the llcc edac driver and passes platform
data to it.

This patchset depends on the LLCC driver, which is part of 4.19 release.

Patch wise description given below:

Patch 1 adds the broadcast base regmap for broadcast writes in llcc.

Patch 2 adds the required changes to register edac driver from llcc driver.

Patch 3 adds the EDAC driver support for QCOM SoCS.

Patch 4 updates the dt bindings of llcc.

Changes since v1:
  * Modified the edac driver
    - Removed duplicate functions that are used to dump the syndrome registers,
      replaced that with a common function and a reg_data datastructure.
    - Removed structure containing function pointers.
    - Addressed comments on error handling to clear the interrupt status.
  * updated Kconfig

Changes since v0:
  * Added EDAC_QCOM config and updated the driver
  * Addressed comments related to indentation and other minor ones
