spi: dw: Replace DWC_HSSI capability with IP-core version checker
Since there is a common IP-core and component versions interface available
we can use it to differentiate the DW HSSI device features in the code.
Let's remove the corresponding DWC_HSSI capability flag then and use the
dw_spi_ip_is() macro instead.
