Subject: [PATCH 0/7] firmware: arm_scmi: imx: Dump syslog and system_info

System Manager firmware provides API to dump board, silicon, firmware
information. It also provides API to dump system sleep, wakeup
information. So add the interface for Linux to retrieve the information:

patch 1 is to add doc for board information which was missed before.

The output as below:
root@...95evk:~# cat /sys/devices/platform/arm-scmi.0.auto/scmi_dev.14/syslog
Wake Vector = 36
Sys sleep mode = 0
Sys sleep flags = 0x00000000
MIX power status = 0x00030017
MEM power status = 0x00014400
PLL power status = 0x00000020
Sleep latency = 764
Wake latency = 3728
Sleep count = 1
root@...95evk:~# cat /sys/devices/platform/arm-scmi.0.auto/scmi_dev.14/system_info
SM Version    = Build 646, Commit 08707569f4
SM Config     = mx95evkrpmsg, mSel=0
Silicon       = i.MX95 B0
Board         = i.MX95 EVK, attr=0x00000000
