[PATCH v2] powerpc: Append linux_banner to exception information in xmon.

[Rashmica Gupta <rashmicy@gmail.com>]

Currently if you are in xmon without an oops etc. to view the kernel
version you have to type "d $linux_banner" - not necessarily obvious. As
this is useful information, append to the output of "e" command.

Example output:
$mon> e
cpu 0x1: Vector: 0  at [c0000000f879ba80]
    pc: c000000000081718: sysrq_handle_xmon+0x68/0x80
    lr: c000000000081718: sysrq_handle_xmon+0x68/0x80
    sp: c0000000f879bbe0
   msr: 8000000000009033
  current = 0xc0000000f604d5c0
  paca    = 0xc00000000fdc0480	 softe: 0	 irq_happened: 0x01
    pid   = 2467, comm = bash
