Due to linux create hwmonN node number, N isn't fixed. So modify to use "" to let thermal.py can correct sysfs. For example, use /sys/bus/i2c/devices/55-0048/hwmon/hwmon/temp1_input to instead of /sys/bus/i2c/devices/55-0048/hwmon/hwmon4/temp1_input
AS7326-56X and AS7726-56X use the same design so both devices have the same problem.
The detailed description below takes AS7326-56X as the example to explain.
Original implementation:
- In platform/broadcom/sonic-platform-modules-accton/as7326-56x/service/as7326-platform-handle_mac.service,
it executes the script file "accton_handle_idt.sh".
- In "accton_handle_idt.sh", it modifies the content of the script file "/etc/init.d/opennsl-modules"
to insert the lines to execute "idt_init.sh" before the command to load broadcom linux kernel module "linux-kernel-bde.ko".
- The script "idt_init.sh" cannot be executed at the first boot of SONiC after installing SONiC under ONIE. This is the reason why all of the ports does not work.
New implementation:
- Let "as7326-platform-handle_mac.service" execute "idt_init.sh".
- Change the content of "as7326-platform-handle_mac.service" to define the service type as "oneshot". Add the settings to ensure "as7326-platform-handle_mac.service" is executed before "opennsl-modules.service".
By setting the service type as "oneshot", it is guaranteed that "opennsl-modules.services" is started only when the forked process to execute the script file "idt_init.sh" is terminated

I2c burst read may failed due to misoperation of ir3570a(A DC-to-DC converter IC).
As #2966, there are 3 more models have this symptom, as7326-56x, as7726-32x, and as9716-32d.
Also correct typo of naming on as7816-64x and as7716-32x.

What I did
Disabling i2c function of ir3570a which may failed i2c tranfer to others.
Close channel of mux after data transfered.
How I did it
Identify version of ir3570, if it's ir3570a, disable its alias i2c address.
Enable parameter of driver i2c_mux_pca954x to close channel on after every access.
How to verify it
Write 08 to offset 0xcf of systom eeprom and execute i2c block read.
It will return error.
plug-in several transceivers and run "show interfaces transceiver presence" and "sfputil show presence". You may see the different result. (But doing this requires updated xcvrd).
