* Improve sunxi fix-a64-timejump.patch
Current patch still throws BUG:
WARNING: CPU: 2 PID: 31 at drivers/clocksource/arm_arch_timer.c:364 sun50i_a64_read_cntpct_el0+0x2c/0x38
Cause: Timer values are required to be exactly the same, while it may increase in between reads. Seems to happen especially during boot
Timer values are like: x2 : 0000000015014561 - x0 : 0000000015014567
Solution: Normalize timer values and return normalized value.
* Add patch for 5.12.y
Note. Small changes on upstream solution:
GENMASK(9, 0 ... -> GENMASK(8, 0 ...
