cxl: Make HDM commit helpers available to reset code

This commit builds generic HDM resource helpers under CONFIG_CXL_RESET so
PCI reset paths can use them when cxl_core is modular. It exports the
necessary lock and commit entry points consumed by cxl_core.

[Severity: Low]
Will defining config CXL_RESET inside the if CXL_BUS block cause an unmet
direct dependency warning during build when CONFIG_CXL_BUS=m?

Because CXL_BUS uses select CXL_RESET, but CXL_RESET inherently inherits
the if CXL_BUS direct dependency, configuring CONFIG_CXL_BUS=m forces the
boolean target CXL_RESET to y while its direct dependency evaluates to m.

Could this be resolved by moving config CXL_RESET outside the if CXL_BUS
block?
