[U-Boot] [PATCH v4 2/2] zlib: add watchdog reset call

[Giuseppe CONDORELLI]

This patch adds watchdog reset call to allow its invokation during decompression
phase. This control was present on old zlib version and here it is
backported for those relevant routines. This patch is sent as a zlib separate
one beacuse it was not tested due to specific board lack.
zlib patches will be unified just in one when this will be validated through
tests.
