ARM: 8340/1: ARMv7-M: Enlarge vector table up to 256 entries
From Cortex-M reference manuals, the nvic supports up to 240 interrupts.
So the number of entries in vectors table is up to 256.
This patch adds a new config flag to specify the number of external interrupts.
Some ifdeferies are added in order to respect the natural alignment without
wasting too much space on smaller systems.
