Instead of arbitrarily deciding whether to enter 4BA mode in the flash chip's declaration, advertise that entering 4BA mode is supported and only enter it if the SPI master supports 4-byte addresses. If not, exit 4BA mode (the chip might be in 4BA mode after reset). If we can't assure the state of 4BA mode, we bail out to simplify the code (we'd have to ensure that we don't run any instructions that can usually be switched to 4BA mode otherwise). Two new feature flags are introduced: * FEATURE_4BA_ENTER: Can enter/exit 4BA mode with instructions 0xb7/0xe9 w/o WREN. * FEATURE_4BA_ENTER_WREN Can enter/exit 4BA mode with instructions 0xb7/0xe9 after WREN. FEATURE_4BA_SUPPORT is dropped, it's completely implicit now. Also, draw the with/without WREN distinction into the enter/exit functions to reduce code redundancy.
