gowin: Add support for OSER primitives
* placement of OSER4, OVIDEO, OSER8 and SER10 primitives is supported;
* primitives are implemented for the GW1N-1, GW1NZ-1, GW1NSR-4C,
GW1NR-9, GW1NR-9C chips;
* the initial support for special HCLK clock wires is implemented to the
extent necessary for OSER primitives to function;
* output to both regular IO and TLVDS_OBUF is supported;
* tricks required for IOLOGIC to work on one side of the -9 and -9C
chips are taken into account;
* various edits, such as using idf() instead of the local buffer.
Compatible with old apicula bases.
