rockchip: roc-rk3399-pc: Set LED only during POR and pwr_key=y
ROC-RK3399-PC has specific set of configurations for
on-board led setup.
Due to easiness for user to know the state of the board
roc-rk339-pc board code will setup the low power led
on/off, and waiting for user to press power key and then
glow full power led.
All this needs to happen only during power-on-reset not
for soft reset or WDT.
Also, it is not a proper usage to ask the user to press
the Power key if the board connected remotely, so add
the environment variable 'pwr_key' to check as well.
So, user need to press Power key only
- during POR
- pwr_key=y

rockchip: Separate the reset cause from display cpuinfo
reset cause is a generic functionality based on the soc
cru registers in rockchip. This can be used for printing
the cause of reset in cpuinfo or some other place where
reset cause is needed.
Other than cpuinfo, reset cause can also be using during
bootcount for checking the specific reset cause and glow
the led based on the reset cause.
So, let's separate the reset cause code from cpuinfo, and
add a check to build it for rk3399, rk3288 since these two
soc are supporting reset cause as of now.

Clearing the status register end of get_reset_cause will end

Some of the Micron SPI NAND devices have the "Continuous Read" feature
enabled by default, which does not fit the subsystem needs.
In this mode, the READ CACHE command doesn't require the starting column
address. The device always output the data starting from the first
column of the cache register, and once the end of the cache register
reached, the data output continues through the next page. With the
continuous read mode, it is possible to read out the entire block using
a single READ command, and once the end of the block reached, the output
pins become High-Z state. However, during this mode the read command
doesn't output the OOB area.
Hence, we disable the feature at probe time.
