IPQ40xx series has a HW pseudo random number generator built in.
It already has a node in the upstream ipq4019.dtsi so we just need to enable it.
Its driver has been rewritten to use crypto API so we dont have char interface like under 4.14 kernel.

DTC was throwing warnings like this:
image-qcom-ipq4018-jalapeno.dtb: Warning (avoid_unnecessary_addr_size): /soc/spi@78b5000/m25p80@0: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
image-qcom-ipq4018-jalapeno.dtb: Warning (avoid_unnecessary_addr_size): /soc/spi@78b5000/spi-nand@1: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
So lets fix this for our downstream boards.

Since 4.19 upstream kernel provides generic SPI-NAND
framework and vendor specific drivers.
Since only users of MT29F are 2 boards with Winbond
W25N01GV SPI-NAND for which support has been backported
from 4.20 we can drop the ever stuck in staging MT29F
driver and instead use the upstream driver.
