ARM: dts: aspeed: clemente: add gpio line name to io expander
The chassis power cycle process requires a forced shutdown before
cutting off the standby power. The SCM CPLD implements a hard shutdown
host function that is controlled through the IO expander in the
Clemente platform.
This change adds a new GPIO line named "shdn_force_l_cpld" to the
PCA9555 IO expander's gpio-line-names at index 10. When asserted,
this GPIO signals the CPLD to pull the HPM's SHDN_FORCE_L pin low,
which triggers a forced host shutdown.
