DONT_SLEEP bit in PMU GLobal control register, if set, wakes up the
microblaze from sleep state. This makes the "sleep" instruction
ineffective by making the MB to toggle between sleep and wake states
in the core loop. So this bit is cleared to prevent such a situation
and ensure that MB wakes up only in case of an interrupt event.

Exception handler is modified to log the ESR and EAR registers
into persistent global storage registers(0,1) and set FW error bit-0.
If bit-0 of FWError group in ERROR_2 register set is configured to do
a SRST,then post reset, SW can read the reason for exception from
these persistent registers.

Basic APIs are provided for modules to send/receive IPI messages.
These are wrappers around IPI driver functions and are intended to
support a common message structure. Currently only a module's IPI ID
is considered.This can be extended to include checksum and other fields in
IPI message and dispatching IPIs based on module id.

Add DAP event handler to PMU Firmware as a new user module and pass on
the handling to respective ROM Handlers.When a DAP wake arrives,
PMU should ACK the DAP Wake using its local registers.
PMU ROM has handlers for these and we will re-use these handlers here.
This module is enabled only if ENABLE_PM is not defined to avoid conflict

If an interrupt occurs without a user defined callback, don't invoke the

Otherwise, unexpected behavior will be seen due to running code from 0x0 (NULL).
Prior to this, it was the responsibility of the user to ensure all callbacks for

RX initialization is not dependent on PLL and reset checks.
- Training will not be initiated until the RX is ready.
The clock is transmitted only once the cable is connected.
- This means that the CPLLs will never lock if no cable is plugged
in resulting in DP RX core initialization time out.
