Add support in the driver to manage power without enabling pm runtime.
UART driver gives control to user space client to vote for clock on/off
by exposing ioctls. These vote clock on/off APIs depend on PM runtime
framework for power related operations.
This change relaxes driver from depending on userspace ioctls to invoke
runtime resume/suspend for basic uart functionality which will now be
done by system suspend/resume. This will block PM framework API's and
use system suspend/resume API for UART on/off.

Commit 54fdb1e448 ("PCIe: ASPM: Save/restore ASPM-L1SS
controls for suspend/resume") restores PCI_L1SS_CTL1, then
PCI_L1SS_CTL2. It should do those in the reverse order, since
the Enable bits are in PCI_L1SS_CTL1. It also restores L1SS
state before we restore the PCIe Capability potentially enabling
ASPM as a whole. Fix the issue by changing order for both save
and restore.

Enabling crash dump (kdump) includes
* prepare contents of ELF header of a core dump file, /proc/vmcore,
using crash_prepare_elf64_headers(), and
* add two device tree properties, "linux,usable-memory-range" and
"linux,elfcorehdr", which represent respectively a memory range
to be used by crash dump kernel and the header's location

Commit 1c3b63b8d8 ("usb: f_fs: Avoid use-after-free of
epfile") fixed use-after-free in ffs_func_eps_disable but
there is still a possiblilty of ffs_epfile_release going
ahead and freeing the buffer while ffs_func_eps_disable has
acquired the spin_lock and initialized local copy of epfile.
Since ffs_epfile_release doesn't have spin_lock protection
for freeing up the read buffer, fix this by putting it under
spin_lock protection as well.
