xlat: introduce XLAT_STYLE_FMT_D

Browse Source 
As there are some possible users for it, apparently.

* defs.h (XLAT_STYLE_FORMAT_MASK): Update the value in order to
accommodate XLAT_STYLE_FMT_D.
(enum xlat_style) <XLAT_STYLE_FMT_D>: New enumeration entity.
(printxval64_d, printxval_d): New function, a shorthand for
printxvals_ex with a single xlat and XLAT_STYLE_FMT_D xlat style.
* xlat.c (sprint_xlat_val): Handle XLAT_STYLE_FMT_D.
