Prevent cs line configuration error in slave mode.
If master mode uses cs-gpio configuration, it should be changed into
non-gpio for CS line in slave mode. Otherwise, slave will receive several
0xFF at the beginning of one transfer especially in dma mode.Signed-off-by: Clark Wang

Add dma configurations in dts files, for imx7ulp and imx8qm.
There is no "edma0" node in fsl-imx8qm-mek(or lpddr4-arm2)-domu.dts.
lpspi0 node has been deleted in these dts files, so delete lpspi3 node.Add edma0a and edma0d for lpspi0 and lpspi3, and enable lpspi0/3 for xen.

For ECSPI test, add these two dts files.
imx6ul-14x14-evk-ecspi.dts: enable ecspi4 function. Because ethernet2
uses the same pins with ecspi4, so disable fec1/fec2.

The main difference for EVKB(SOMB REVA + EVKB RevA) comparing with
EVK(SOM RevB2 + BB RevB1):
- SOMB REVA change: WIFI module Cypress 1DX replace with QCA 1PJ
- BB EVKB RevA change: MIPI connectorThe EVKB board focus on default functions on board without rework,
WIFI/BT, and MIPI feature test. Currently, the patch don't consider
other functions with rework needed.Reviewed-by: Haibo Chen

The i.MX6ULZ is sw compatible with i.MX6ULL, and the EVK board has
no big difference, so include i.mx6ull evk dts file do reduce code
redundancy.Signed-off-by: Bai Ping
-
The i.MX6ULZ is new SOC of the i.MX6 series. it
is SW compatile with i.MX6ULL, so most of the code
can be reuse from i.MX6ULL. To maximum the SW reuse,
i.MX6ULZ don't have an independent SOC id in anamix.
so a dummy ID is used to identify it.Signed-off-by: Bai Ping

According to the latest datasheet(Rev,1.3 08/2018). the VDD_SOC voltage
need to be updated to 1.225V when cpu running at 900MHz. we need to add
25mV margin to cover the board tolerance and IR drop. so the voltage
need to be updated to 1.25V.Signed-off-by: Bai Ping
