Increased max number of files,fds statically supported by pk.
The SPECINT benchmark 445.gobmk reads in a lot of files and would
sometimes fail due to being unable to open more files.

Implement draft of new calling convention
Here is the new syscall ABI:
syscall number in a7
args in a0 - a6
return value in a0
Here is the integer register map:
x0 -> x0
x1 -> ra
x2 -> sp
x3 -> tp
x4 -> gp
x5 -> t0
x6 -> t1
x7 -> t2
x8 -> s0
x9 -> s1
x10 -> a0
x11 -> a1
x12 -> a2
x13 -> a3
x14 -> a4
x15 -> a5
x16 -> a6
x17 -> a7
x18 -> s2
x19 -> s3
x20 -> s4
x21 -> s5
x22 -> s6
x23 -> s7
x24 -> s8
x25 -> s9
x26 -> s10
x27 -> s11
x28 -> t3
x29 -> t4
x30 -> t5

Let timer interrupt stay set on pk start (IP[7]).
Otherwise, the HW will trip the timer interrupt 4B cycles later and thus not match spike.

Changes to allow spike & RTL behavior to better match each other.
- EI turned off on sys_exit.
- IM/IP cleared on start.
- badvaddr only saved to tf on page faults.
