zynqmp: Add bakery_lock to protect APU_PWRCTRL register access

Access to APU_PWRCTRL register is protected during suspend/wakeup pocedure
in order to save valid state. If more than one CPU is accessing this register
it can be left in corrupted state during read-modify-write process.

zynqmp: Put pm_secure_lock in coherent memory region

DEFINE_BAKERY_LOCK() macro is used to put lock in coherent memory region.
ARM Trusted Firmware design guide, chapter 11 states that bakery_lock data
structures should be allocated in coherent memory region because it is
accessed by multiple CPUs with mismatched shareability, cacheability and
memory attributes.

Implement generic delay timer

Add delay timer implementation based on the system generic counter.
This either uses the platform's implementation of
`plat_get_syscnt_freq()` or explicit clock multiplier/divider values
provided by the platform.

The current implementation of udelay has been modified to avoid
unnecessary calculations while waiting on the loop and to make it
easier to check for overflows.
