When CONFIG_MIPS_CPS_NS16550 is enabled, some register state is dumped
to the UART when an exception is taken via the BEV on secondary cores.
EJTAG exceptions are architecturally expected to be handled by the BEV
even when Status.BEV is 0. This effectively means that if userland
executes an sdbbp instruction on a secondary core then the kernel dumps
register state to the UART even though the exception is perfectly normal
& expected. Prevent this by simply not dumping information to the UART
for EJTAG exceptions.

Introduce support for bringing up Virtual Processors in MIPSr6 systems
as CPUs, much like their VPE parallel from the now-deprecated MT ASE.
The existing mips_cps_boot_vpes function fits the MIPSr6 architecture
pretty well - it can now simply write the mask of running VPs to the
VC_RUN register, rather than looping through each & starting or stopping
as appropriate as is done for VPEs from the MT ASE. Thus the VP support
is in general an extension & simplification of the existing MT ASE VPE
(aka SMVP) support.

In preparation for supporting MIPSr6 multithreading (ie. VPs) which will
begin execution from the core reset vector, skip core level setup if the
core is already coherent. This is never the case when a core is first
started, since boot_core explicitly clears the cores GCR_Cx_COH_EN
register, and always the case when secondary VPs start since the first
VP to start will have enabled coherence after initialising the core &
its caches.
One notable side effect of this patch is that eva_init gets called
slightly earlier, prior to mips_cps_core_init rather than after it.

Current ath79 clock.c code does not read reference clock and
pll setup from devicetree. E.g. you can set any clock rate value
in board DTS but it will have no effect on the real clk calculation.
This patch fixes some AR9132 devicetree clock support defects:
* clk initialization function ath79_clocks_init_dt_ng()
is introduced; it actually gets pll block base register
address and reference clock from devicetree;
* pll register parsing code is moved to the separate
ar724x_clk_init() function; this function
can be called from platform code or from devicetree code.
Also mips_hpt_frequency value is set from dt, so the appropriate
clock parameter is added to the cpu@0 devicetree node.
The same approach can be used for adding AR9331 devicetree support.

Here are some Sascha Hauer's arguments for using aliases in the dts
files:
- using aliases reduces the number of indentations in dts files;
- dts files become independent of the layout of the dtsi files
(it becomes possible to introduce another bus {} hierarchy between
a toplevel bus and the devices when you have to);
- less chances for typos. if &i2c2 does not exist you get an error.
If instead you duplicate the whole path in the dts file a typo
in the path will just create another node.
