[PATCH v4 0/2] KTD2026 indicator LED for X86 Xiaomi Pad2

[Kate Hsuan]

This patch added the support for Xiaomi Pad2 indicator LED. This work
included two parts.
1. Added the KTD2026 swnode description to describe the LED controller.
2. Migrated the original driver to fwnode to support x86 platform.

Moreover, the LED trigger is set to bq27520-0-charging for Xiaomi Pad2
so the LED will be turned on when charging.

Changes in v4:
1. Fix double casting.
2. Since force casting a pointer value to int will trigger a compiler
   warning, the type of num_leds was changed to unsigned long. 

Changes in v3:
1. Drop the patch "leds-ktd202x: Skip regulator settings for Xiaomi
   pad2"

Changes in v2:
1. Typo and style fixes.
2. The patch 0003 skips all the regulator setup for Xiaomi pad2 since
   KTD2026 on Xiaomi pad2 is already powered by BP25890RTWR. So, the
   sleep can be removed when removing the module.
