feature(psram): add 80Mhz mode for psram. Since we have flash rom code patch now, we can fix the compatibility issue between SPI APIs and psram.
1. add qio enable option in bootloader for GD25LQ32C flash.
2. add option for psram mode: 40m+40m, 80m+40m, 80m+80m.
3. fix bugs in spi_flash_rom_patch

After rebasing, it was found out that flushing the cache drops the writeback-pending psram cache lines on the ground. We now evict these by reading 64/128K of memory before flushing the cache. Also fixes a snafu in psram cache mode (inverted hi/lo and even/odd selectors) as well as an option to not let the heap allocator touch the psram.
