[PATCH 1/7] coresight: move struct tracectx inside etm driver

[Alexander Shishkin <virtuoso@slind.org>]

This is done so as to be able to make use of the coresight components'
registers in assembler code (like omap sleep code). Also, there shouldn't
be any users of this structure outside the etm driver.
