soc: imx: imx8m-blk-ctrl: set LCDIF panic read hurry level

Browse source

When the LCDIF block signals a panic condition due to the display FIFO
falling below the threshold, the priority at the NoC level is boosted
to the value set in the LCDIF_ARCACHE_CTRL register of i.MX8MP mediamix
blk-ctrl. Same as all other blk-ctrl registers this register is reset
when the domain is powered down. Initialize the panic hurry levels for
both LCIF interfaces to the maximium priority (same as downstream TF-A
and proven to work with the other priorities set in the interconnect
driver) when coming back from power down.
