quark_se: Add restore info shared memory to linker

Browse source 
A new shared memory has been added to the qmsi bootloader
in order to handle the restore flow and jump to
the restore trap where context is restored.

Add the new entry to the QUARK SE C1000 linker file
and new kconfig options:
- CONFIG_BSP_SHARED_RAM_ADDR to set the address of the
  shared memory.
- CONFIG_BSP_SHARED_RAM_SIZE to set the size of the
  shared memory.

This is only enabled with CONFIG_SYS_POWER_DEEP_SLEEP.
