samsung-i927: update kernel to 5.2.1, more updates (!452)
- OTG support
- Charger
- WiFi 5GHz
- RTC bug "fixed" (always-on interrupt - made device overheat!)
- Kernel version bumped to 5.2.1
- Memory timings
- New WM8994 codec board driver (fixes suspend/resume)
- Camera's regulator supported now (saves power at least!)
- Updated panel driver (still not in mainline, idk why)
- MHL support in kernel (fixes boot times and screen, currently disabled in X,
  not tested)
- Other minor kernel chagnes

Subject: [PATCH] ARM: dts: tegra20-glide: Fix audio power binding
The LDO definition in wm8994 node is used for internal LDOs, but not for
powering the chip, so we use the fixed regulator to resolve this.
All regulators of wm8994 are defined to suppress messages in dmesg.
