In IPQ5424, the bootloader collects the system RAM contents upon a crash
for post-morterm analysis. If we don't reserve the memory region used by
the bootloader, linux will consume it. Upon the next boot after a crash,
the bootloader will be loaded in the same region, which could lead to the
loss of some data. sometimes, we may miss out critical information.
Therefore, let's reserve the region used by the bootloader.

Serial engines 4 and 5 on the IPQ5424 support SPI. Serial engine 4 is
exclusively dedicated to SPI, whereas serial engine 5 is firmware based
and supports SPI, I2C, and UART.
The SPI instance operates on serial engine 4, designated as spi0, and on
serial engine 5, designated as spi1. Add both the spi0 and spi1 nodes.
