spi: Fix dat_i_l constraints

Browse Source 
No cells matched 'get_cells -hierarchical -filter {NAME =~*/spi_rxtx/dat_i_l*}'. [build/microwatt_0/src/microwatt_0/fpga/arty_a7.xdc:42]

The signal is in it's own process so the net name ends up being
spi_rxtx/input_delay_1.dat_i_l_reg.

After this change the log shows:

Applied set_property IOB = TRUE for soc0/\spiflash_gen.spiflash /spi_rxtx/\input_delay_1.dat_i_l_reg . (constraint file  fpga/arty_a7.xdc, line 42).
