spi: k64: Remove the k64 spi driver

Now that we have a more generic mcux spi driver that can be used across
multiple Kinetis SoCs, remove the specific k64 spi driver.

- * Device configuration
- *
- * Device-independent configuration:
- * Bits [0 : 11] in the config parameter of the spi_configure() API are defined
- * with the following fields.
- *
- * SCK polarity     [ 0 ]       - SCK inactive state (0 = low, 1 = high)
- * SCK phase        [ 1 ]       - Data captured/changed on which SCK edge:
- *                              -   0 = leading/following edges, respectively
- *                              -   1 = following/leading edges, respectively
- * loop_mode        [ 2 ]       - Not used/Unsupported
- * transfer_mode    [ 3 ]       - First significant bit (0 = MSB, 1 = LSB)
- * word_size        [ 4 : 7 ]   - Size of a data train in bits
- * unused           [ 8 : 11 ]  - Unused word_size field bits
- *
- * Device-specific configuration:
- * Bits [12 : 31] in the config parameter of the spi_configure() API are
- * available, with the following fields defined for this device.
- *
- * PCS0-5 polarity  [ 12 : 17 ] - Periph. Chip Select inactive state, MCR[PCSIS]
- *                              -   (0 = low, 1 = high)
- * Continuous SCK   [ 18 ]      - Continuous serial clocking, MCR[CONT_SCKE]
- *                              -   (0 = disabled, 1 = enabled)
- * Continuous PCS   [ 19 ]      - Continuous selection format, PUSHR[CONT]
- *                              -   (0 = disabled, 1 = enabled)
- *
- * Note that the number of valid PCS signals differs for each
- * K64 SPI module:
- * - SPI0 uses PCS0-5;
- * - SPI1 uses PCS0-3;
- * - SPI2 uses PCS0-1;
