This patch is the extension of following upstream commit to fix
the race condition between get_task_mm() and core dumping
for IB->mlx4 and IB->mlx5 drivers:
commit 04f5866e41fb ("coredump: fix race condition between
mmget_not_zero()/get_task_mm() and core dumping")'

The core dumping code has always run without holding the mmap_sem for
writing, despite that is the only way to ensure that the entire vma
layout will not change from under it. Only using some signal
serialization

The clock which has been used here is not about the phy but the pcie port.
It has been properly handled into host pcie driver code. Hence, remove it
from here which is the correct thing to do.

This driver has dependencies on mt7621-gpio and mt7621-pci-phy which
are init in later stages. Hence, when this driver is probed it is always
returning 'EPROBE_DEFER' and being initialized afterwards. Use function
'module_init' to just initialize later.
