These devices will not reliabily report the proper devid and vendorid
when reading it is read directly from the pci config space.
It can be read but shouldn't be compared against some fixed value like
the one stored in pcie.yaml.
Since this makes pcied unhappy, the simplest path forward is to just
remove this device from monitoring.
After upgrade to brcmsai 8.1, the sdk running environment (container) recommended with mininum memory size as below
TH4/TD4(ltsw) uses 512MB
TH3 used 300MB
Helix4/TD2/TD3/TH/TH 256 MB
Base on this requirement, adjust the default syncd share memory size and set the memory size for special ACISs in platform_env.conf file for different types of Broadcom ASICs.
How I did it
Add the platform_env.conf file if none of it for broadcom platform (base on platform_asic file)
Add the 'SYNCD_SHM_SIZE' and set the value
for ltsw(TD4/TH4) devices set to 512M at least (update the platform_env.conf)
for Td2/TH2/TH devices set to 256M
for TH3 set to 300M

How to verify it
verify the image with code fix
Check with UT
Check on lab devices
On a problematic device which cannot start successfully
Run with the command
$ cat /proc/linux-kernel-bde

Module parameters:
maxpayload=128
usemsi=0
dmasize=32M
himem=(null)
himemaddr=(null)
DMA Memory (kernel): 33554432 bytes, 0 used, 33554432 free, local mmap

Add most configuration files for the DCS-7050PX4-32S and DCS-7050DX4-32S.
This review only contains platform configuration files, dataplane ones will follow in future change.
