msm: mdss: add ESD status support for NT35596 panel

In ESD thread implementation using DSI status read method,
currently we check the read value of only one register from
the panel. For NT35596 panel, the expected read back value
for the health status register is 8 bytes. Add support for
ESD status for this NT35596 panel accordingly.
