[PATCH RESEND] thermal/drivers/brcmstb_thermal: Use max to simplify brcmstb_get_temp

[Thorsten Blum <thorsten.blum@linux.dev>]

Use max() to simplify brcmstb_get_temp() and improve its readability.
Since avs_tmon_code_to_temp() returns an int, change the data type of
the local variable 't' from long to int.  No functional changes.
