arm-bsp/trusted-firmware-a: N1SDP trusted boot

Browse Source 
This commit configures trusted-firmware-a for TBBR bootflow on N1SDP as follows:
* Trusted Firmware is upgraded to 2.7.0 for the N1SDP only
* Trusted boot is enabled.
* Generation of root-of-trust is enabled
* All TB images (BLx, DTBs) are built
* uefi.bin is specified as the BL33 image
* BL2, BL31, BL33 are signed and stored in the FIP
* N1SDP platform sources are patched to increase max size BL2 and reduce max size of BL1

Subject: [PATCH] arm-bsp/trusted-firmware-a: N1SDP trusted boot
Increase max size of BL2 on N1SDP by 4KB to enable trusted boot
Decrease max size of BL1 on N1SDP by 8KB so BL1/BL2 fits above BL31 progbits
