reworked cavium octeon 'bootoctlinux' argument support patch

The patch has been reworked to support single letter boot flags and factors out
the code that sets bits in the boothowto variable. Other machdep code that
needs to set boothowto flags can pass the "-<bootflags>" argument it gets from
the boot loader into the new "boothowto_parse" function.

These are a few examples on how I use this on my edgerouter lite.

Boot normally from U-Boot:

  Octeon ubnt_e100# bootoctlinux ${loadaddr} coremask=0x3

Boot to single user mode:

  Octeon ubnt_e100# bootoctlinux ${loadaddr} coremask=0x3 -s

Specify kernel environment variables:

  Octeon ubnt_e100# bootoctlinux ${loadaddr} coremask=0x3
vfs.root.mountfrom=ufs:/dev/da0s2a foo=bar

Combination of boot flags and kenv:

  Octeon ubnt_e100# bootoctlinux ${loadaddr} coremask=0x3
vfs.root.mountfrom=ufs:/dev/da0s2a -s
