Fix odroid (#1795)

Browse Source 
* Address Odroid XU4 current stability issues. (#1766)

* Address stability issues, update configuration. 
* Cleanup - remove not needed patches
* Add upstream patches

Board survived regular stress testing while previous config/version hanged instantly.

* Upstream patches for a few legacy kernels

From: Colin Ian King <colin.king@canonical.com>
The multiplication of opp_freq by MHZ is performed using unsigned int
multiplication however the result is being passed into a function where
the frequency is an unsigned long, so there is an expectation that the
result won't fit into an unsigned int. Fix any potential integer overflow
my making opp_freq an unsigned long. Also change from %u to %lu format
specifiers
Addresses-Coverity: ("Unintentional integer overflow")
Fixes: 5ea428595cc5 ("soc: samsung: Add Exynos Adaptive Supply Voltage driver")

Convert DWC2 bindings to DT schema format using json-schema.
DWC2 is widely use but a couple of compatibles and properties
