arm-bsp/trusted-firmware-m: corstone1000: Increase PS size

Browse Source 
Increase the size of PS storage in Secure Flash.

The SecureBoot and Security Interface Extension (SIE) tests for MPS3
are failing when the Secure Flash runs out of memory. The frequency
of the errors is at least 50-60%. The aim of this is to increase
the size of PS storage in Secure Flash, so as to minimize
the possibilities of it to run out of memory.

FLASH_PS_AREA_SIZE is increased.
