The reset width register controls how the pulse on the SoC's WDTRST{1,2}
pins behaves. A pulse is emitted if the external reset bit is set in
WDT_CTRL. On the AST2500 WDT_RESET_WIDTH can consume magic bit patterns
to configure push-pull/open-drain and active-high/active-low
behaviours and thus needs some special handling in the write path.
As some of the capabilities depend on the SoC version a silicon-rev
property is introduced, which is used to guard version-specific
behaviour.
