...
Also remove unused slot_status - maintains CSR alignment now that
slot_control is 64 bit (two 32bit registers).

cores/spi_mmap: fix data if bus width > length
...
Details:
* 32bit bus write to 8 and 16bit MSB first slot resulted
in shifted data on mosi.
* 32bit read from 8 and 16bit LSB first slot resulted
with shifted data in fifo.
Fixes 2 tests - all current tests now pass.

soc/cores/spi_mmap: adjust CSR mapping to better suit drivers
...
Currently the TX_RX_ENGINE CSR register lives below the
slot registers which are dynamic in length (based on how
many slots (chip selects) are configured in the gateware).
Move the TX_RX_ENGINE CSR to above the SLOT configuration
registers so TX_RX_ENGINE never moves.
This makes for an easier and cleaner driver.

build/efinix/platform: fix get_pin_name()
...
get_pin_name did not include the resource index, so additional core
instances were generated with identical pin names. See below for
examples.
Also only adds slice index for slices with more than one io for cleaner
naming.
