Support SIM permanently disabled state.

SIM card can get permanently disabled due to too many
PUK retries. The PERM_BLOCKED pin state of SIM application
represents this state.

This change decodes permanent disabled state and broadcasts it
via ICC_ABSENT intent with PERM_DISABLED reason. It also update
the lockscreen to show the prompt message.
