Commit 'ARM: zynq: Remove hotplug.c'
(caf86a73eab4132f870e883216850d9eee40b04b) was supposed to remove
hotplug.c - but it didn't. It moved all content from
hotplug.c elsewhere and removed its entry from the Makefile, but missed
to actually remove the whole file. Remove it now.

The hotplug code contains only a single function, which is an SMP
function. Move that to platsmp.c where all other SMP runctions reside.
That allows removing hotplug.c and declaring the cpu_die function
static.

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
exit coherency.

zynq_platform_do_lowpower() does never return. Hence remove
all code which relies on that function returning and consolidate the
remains.
