From: Tien Fong Chee <tien.fong.chee@intel.com>
Drivers for reset manager is restructured such that common functions,
gen5 drivers and Arria10 drivers are moved to reset_manager.c,
reset_manager_gen5.c and reset_manager_arria10.c respectively.

From: Tien Fong Chee <tien.fong.chee@intel.com>
The drivers is restructured such common functions, gen5 functions. and
arria10 functions are moved to misc.c, misc_gen5 and misc_arria10
respectively.

To: u-boot
From: Tien Fong Chee <tien.fong.chee@intel.com>
The drivers is restructured such common functions, gen5 functions, and
arria10 functions are moved to clock_manager.c, clock_manager_gen5 and
clock_manager_arria10 respectively.
