86ce9a340e mips: mt7620: fallback to SDRAM when syscfg0 does not have a valid value for the memory type 
Mediatek MT7620 SoC has syscfg0 bits where it sets the type of memory being used.
However, sometimes those bits are not set properly (reading "11"). In this case, the SoC assumes SDRAM.
The patch below reflects that.

1df7addb96 MIPS: ralink: add MT7621 support 
MT7621 is based on a 1004k core. This patch adds support for the SoC. The
timer and IRQ is just boiler plate as GIC has recently been moved to
generic places in the kernel and just works.

d631fc6070 MIPS: Create a common <asm/mach-generic/war.h> 
11 platforms require at least one of these workarounds to be enabled; 22
platforms do not.  In the latter case we can fall back to a generic version.

Note that this also deletes an orphaned reference to RM9000_CDEX_SMP_WAR.

ded1e9d727 MIPS: ralink: mt7620: Improve clock frequency detection 
The current code assumes that the peripheral clock always
runs at 40MHz which is not true in all configuration. The
peripheral clock can also use the reference clock instead
of the fixed 40MHz rate. If the reference clock runs at a
different rate, various peripheries are behaving incorrectly.

Additionally, the currectly calculated system clock is also
wrong. The actual value what the code computes is the rate
of the DRAM which can be different from the system clock.

Add new helper functions to get the rate of the different
clocks and use the correct values for the registered clock
devices.
