In order to use minimum of hard coded values common to LKD and F/W
a dynamic method to work with PLLs is introduced in this patch.
Formerly asic specific PLL numbering is now common for all asics.
To be backward compatible a bit in dev status is defined, if the bit is
not set LKD will keep working with old PLL numbering.

added to notify the driver on such event. In which case the driver
performs hard reset.

Stop-on-error mode in DMA is useful as it stops the transaction
immediately upon error e.g. page fault.
But it may cause the next command submission to fail as is leaves the DMA
in unstable state.
Therefore we remove the stop-on-error configuration from the DMA.
Stop-on-err is still available for debug.

This patch adds the ASIC-specific function for GOYA to configure the
coresight components.
Most of the components have an enabled/disabled flag, depending on whether
the user wants to enable the component or disable it.
For some of the components, such as ETR and SPMU, the user can also
request to read values from them. Those values are needed for the user to
parse the trace data.
The ETR configuration is also checked for security purposes, to make sure
the trace data is written to the device's DRAM.

This patch adds the H/W queues module and the code to initialize Goya's
various compute and DMA engines and their queues.
Goya has 5 DMA channels, 8 TPC engines and a single MME engine. For each
channel/engine, there is a H/W queue logic which is used to pass commands
from the user to the H/W. That logic is called QMAN.
There are two types of QMANs: external and internal. The DMA QMANs are
considered external while the TPC and MME QMANs are considered internal.
For each external queue there is a completion queue, which is located on
the Host memory.
The differences between external and internal QMANs are:
1. The location of the queue's memory. External QMANs are located on the
Host memory while internal QMANs are located on the on-chip memory.
2. The external QMAN write an entry to a completion queue and sends an
MSI-X interrupt upon completion of a command buffer that was given to
it. The internal QMAN doesn't do that.
