Subject: [PATCH V4 0/5] gpio-xilinx: Update on xilinx gpio driver

This patch series does the following:
-Simplify with dev_err_probe().
-Reduce spinlock array to array.
-Add interrupt support
-Add support for suspend and resume
-Add check for gpio-width
---
Changes in V4:
-Created new patch to simplify code with dev_err_probe().
-Updated minor review comments.
-Created new patch to check gpio-width.
Changes in V3:
-Created separate patch to arrange headers in sorting order.
-Updated dt-bindings.
-Created separate patch for Clock changes and runtime resume.
 and suspend.
-Created separate patch for spinlock changes.
-Created separate patch for remove support.
-Fixed coverity errors.
-Updated minor review comments.

Changes in V2:
-Added check for return value of platform_get_irq() API.
-Updated code to support rising edge and falling edge.
-Added xgpio_xlate() API to support switch.
-Added MAINTAINERS fragment.

Tested Below scenarios:
-Tested Loop Back.(channel 1.0 connected to channel 2.0)
-Tested External switch(Used DIP switch)
-Tested Cascade scenario(Here gpio controller acting as
 an interrupt controller).
