Rebased. Leave the remaining fix to me.🤗

Changes (mainly in d4cb3e6)

• Define some enums in metapac crate (hpm-data commit: andelf/hpm-data@91d96e7)
• rename addr_width data_width to _phrase for improved clarity and consistency.
• Remove unused enums
• Incorporated the SpiMode enum and the MODE_0 constant from the embedded-hal crate, aligning the implementation with established standards.
• Group timing config into Timings. The field enum types might be stripped out as well(in future refactor)

Final changes

• CS pins are bonded to the QSPI driver, not the ordinary SPI driver(leaving it a SpiBus)
• transfer and transfer_inplace are fixed, leaving some minor optimization undone
• The bug for tx is located: Due to the L1 cache being enabled, blocking_write returns very early before fifo finishes writing. So it must wait for fifo empty(I choose spiactive for better busy/idle wait)
• Freq calc is changed, if a specific freq is not possible, a lower one(higher clk_div) will be selected
• Remove most enum definitions. use "word size" definition from the dma part
