For the compatibility of NXP internal legacy kernel before 4.19 which
is based on uart ram script and upstreaming kernel based on uart rom
script, add both uart ram/rom script in latest sdma firmware. By default
uart rom script used.
Besides, add two multi-fifo scripts for SAI/PDM on i.mx8m/8mm and add
back qspi script miss for v4(i.mx7d/8m/8mm family, but v3 is for i.mx6).
rom script:
uart_2_mcu_addr
uartsh_2_mcu_addr /* through spba bus */
am script:
uart_2_mcu_ram_addr
uartsh_2_mcu_ram_addr /* through spba bus */
