* Add PIN_EN1V8 (1V8 work fine 1V8 LED is set to ON), and PIN_BOOT0, 1, 2 & 3(read only).

Browse Source 
* Fixed wait() by using volatile else the loop was removed by GCC.
Tested it with SPIFI work fine:
SPIFI tested with LPCXpresso+NXP LPC Link (from LPCXpresso Board LPC1769 Debugger)
 -> Program Flash with Flash Driver LPC1850A_4350A_SPIFI.cfx
     -> Select file: firmware\blinky\blinky.bin
     -> Base address 0x14000000 & option Erase only required pages
