[202012][Mellanox] Place FW binaries under platform directory instead of squashfs (#13890)

Browse Source 
Upgrade from old image always requires squashfs mount to get the next image FW binary. This can be avoided if we put FW binary under platform directory which is easily accessible after installation:

admin@r-spider-05:~$ ls /host/image-fw-new-loc.0-dirty-20230208.193534/platform/fw-SPC.mfa
/host/image-fw-new-loc.0-dirty-20230208.193534/platform/fw-SPC.mfa
admin@r-spider-05:~$ ls -al /tmp/image-fw-new-loc.0-dirty-20230208.193534-fs/etc/mlnx/fw-SPC.mfa
lrwxrwxrwx 1 root root 66 Feb  8 17:57 /tmp/image-fw-new-loc.0-dirty-20230208.193534-fs/etc/mlnx/fw-SPC.mfa -> /host/image-fw-new-loc.0-dirty-20230208.193534/platform/fw-SPC.mfa

- Why I did it
202211 and above uses different squashfs compression type that 201911 kernel can not handle. Therefore, we avoid mounting squashfs altogether with this change.

- How I did it
Place FW binary under /host/image-/platform/mlnx/, soft links in /etc/mlnx are created to avoid breaking existing scripts/automation.
/etc/mlnx/fw-SPCX.mfa is a soft link always pointing to the FW that should be used in current image
mlnx-fw-upgrade.sh is updated to prefer /host/image-/platform/mlnx location and fallback to /etc/mlnx in squashfs in case new location does not exist. This is necessary to do image downgrade.

- How to verify it
Upgrade from 201911 to 202012
202012 to 201911 downgrade
202012 -> 202012 reboot
ONIE -> 202012 boot (First FW burn)
