drivers: intel: mn: mclk sources
All MCLKs share the same source clock, so we need to track it
prevent case in which next SSP config would override source clock
for previous SSP config.

drivers: intel: mn: bclk sources
All BCLKs that use M/N share the same source clock, so we need to
track sources for each BCLK to prevent case in which next SSP config
would override source clock for previous SSP config.
Since cAVS 2.0, all clocks go through M/N, bypassing XTAL is
no longer supported.
For earlier version MN driver checks if XTAL can be used if it
would result in more efficient settings.
As a result it fixes ECS-related code for cAVS 2.0+ and is backwards
compatible with previous logic when there is only SSP0 used.
Previously topologies that used more than 1 SSP could override
source clock for previously configured SSP ports, now it will try
to use current clock with M/N or report error.

drivers: intel: mn: spinlock for registers access
Single M/N register can manage multiple MCLKs BCLKs for mulitple
clients that's why access to them should be synchronized.

ipc: use ipc_get() instead of global pointer
Uses ipc_get() to retrieve ipc structure pointer instead
of global pointer. This way we have one point of access
and avoid unnecessary cache accesses.
