Gregory Nutt 8c00e43c1a arch/z80/src/ez80: Fix eZ80F92 Interrupt Controller 
The eZ80F92 interrupt controller is very different from the eZ80F91.  The eZ80F91 has:

1. Four byte interrupt vectors
2. The vector base address register is 16-bit so the vector table can lie in RAM

Whereas the eZ80F92 has:

1. Two byte interrupt vectors
2. An 8-bit vector base address

This means that the vectors must lie in the first 16-bits of FLASH and there must be a "trampoline" to get to interrupt handlers outside of the first 64-Kb of FLASH.
