Avoid races and add synchronisation between the arch specific
kill and die routines.
The same synchronisation issue was fixed on IMX platform
by this commit:
"ARM: imx: fix sync issue between imx_cpu_die and imx_cpu_kill"

As there is no Power management unit on this board, it is not possible to power
down a core, just WFI is allowed. There is no point to invalidate the cache and

Original gpt per clk parent is from ipg_per clk which
may be scaled when system enter low bus mode, as ipg
clk will be lower in low bus mode, to keep system clk
NOT drift, select gpt per clk parent from OSC which
is at fixed freq always.
On i.mx6qdl, add a osc_per clk source for i.mx6q
TO > 1.0 and all i.MX6dl SoC.
On i.mx6sx, just make gpt per clk from OSC.

Passing '0x80000000' to the pin configuration means that kernel will skip the
IOMUXC_SW_PAD_CTL configuration and will use whathever values come from the
bootloader.
Instead of relying on the bootloader setup, let's configure it in the kernel to
have predictable settings.
'0x1b0b0' is the default POR value for all these pins and has also been verified
that the pins are using this value by manually inspecting the IOMUXC_SW_PAD_CTL
registers, so no functional change has been made.
