realtek: Convert incorrect v5.10 patches

OpenWRT's developer guide prefers having actual patches so they an be
sent upstream more easily.

However, in this case, Adding proper fields also allows for `git am` to
properly function. Some of these patches are quite old, and lack much
traceable history.

This commit tries to rectify that, by digging in the history to find
where and how it was first added.

It is by no means perfect and also shows some patches that should have
been long gone.

+Subject: [PATCH] realtek: Replace the RTL9300 generic timer with a CEVT timer
+
+The RTL9300 has a broken R4K MIPS timer interrupt, however, the
+R4K clocksource works. We replace the RTL9300 timer with a
+Clock Event Timer (CEVT), which is VSMP aware and can be instantiated
+as part of brining a VSMTP cpu up instead of the R4K CEVT source.
+For this we place the RTL9300 CEVT timer in arch/mips/kernel
+together with other MIPS CEVT timers, initialize the SoC IRQs
+from a modified smp-mt.c and instantiate each timer as part
+of the MIPS time setup in arch/mips/include/asm/time.h instead
+of the R4K CEVT, similarly as is done by other MIPS CEVT timers.

+Subject: [PATCH] realtek: don't unmask non-maskable GPIO IRQs
+
+On uniprocessor builds, for_each_cpu(cpu, mask) will assume 'mask'
+always contains exactly one CPU, and ignore the actual mask contents.
+This causes the loop to run, even when it shouldn't on an empty mask,
+and tries to access an uninitialised pointer.
+
+Fix this by wrapping the loop in a cpumask_empty() check, to ensure it
+will not run on uniprocessor builds if the CPU mask is empty.

+
+This patch backports "irq-realtek-rtl" driver to Kernel 5.10 from 5.12.
+"MACH_REALTEK_RTL" is used as a platform name in upstream, but "RTL838X"
+is used in OpenWrt, so update the dependency by the additional patch.
