Follow the IOExpander_Base pull API of M5Unified 0.2.21

M5Unified 0.2.21 replaced IOExpander_Base::setPullMode(pin, bool) and
enablePull(pin, bool) with setPullMode(pin, gpio_pull_t), so the library no
longer compiled against it.

Select the pull-up setup form from M5UNIFIED_VERSION_* so the library builds
against both 0.2.20 and 0.2.21; the register state (pull-up selected and
enabled) is the same in both forms.
