Gowin. BUGFIX. BSRAM SP separation. (#1622) 
* Gowin. BUGFIX. BSRAM SP separation.

The new SP cell must inherit the byte size - 8 or 9 bits.

Signed-off-by: YRabbit <rabbit@yrabbit.cyou>

* Gowin. Byte Enables processing in SP.

Single Port with a data width of 32/36 is internally configured as Dual
Port with 16/18. Even and odd words are processed separately by ports A
and B.

With the advent of byte enable support, it became necessary to switch
these signals differently.

TG c46f2bbd86 ice40: Explicitly connect CIN when legalizing carry chain 
This connection is implicit as it is hardwired in the hardware.

Gowin. Implemenet special ADC IO. (#1598) 
The TLVDS_IBUF_ADC IO primitives have been implemented, which provide a
signal for ADC bus 2. These differential IO primitives also have an
additional input that allows them to be disabled, thereby providing
dynamic switching of the signal source for the ADC.

Gowin. Implement ADC. (#1597) 
ADC support for GW5A-25 chips has been added.

The inputs of this primitive are fixed and do not require routing,
although they can be switched dynamically.

The .CST file also specifies the pins used as signal sources for the
bus0 and bus1 ADC buses.

gatemate: handle default parameters for IO (#1595) 
* gatemate: handle default parameters for IO

This is probably a VHDL specific issue.  In VHDL, there is no
black-box. Primitive instantiations are done using VHDL component
instantiations and the component must have been declared with all its
ports and parameters (generic).  Currently the components are
translated from cells_sim.v and cells_bb.v

If a user doesn't override a parameter, the default value is used
instead.  As a consequence, nextpnr can have 'UNDEFINED' for DRIVER
or SLEW parameters of CC_IOBUF.  I think this is a main difference
with verilog, where unspecified parameters do not appear.

With this change, the UNPLACED value of PIN_NAME and UNDEFINED value
of DRIVE are simply ignored.

* gatemate/pack_io.cc: also handle UNDEFINED for id_SLEW

Since ctx->getArchArgs() no longer returns architecture-specific
arguments, we read the args field directly.
