Will be used to get HyperRAM characteristics and also to configure latency and enable varialble latency.

Untested yet.

Andrew Dennison 0cb101da25 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.

("i2c", 0,
    Subsignal("scl", Pins(...)),
    Subsignal("sda", Pins(...)),
),
("i2c", 1,
    Subsignal("scl", Pins(...)),
    Subsignal("sda", Pins(...)),
),

Before:
    output wire          i2c0_oe,
    input  wire          i2c0_scl,
    input  wire          i2c0_sda,
    input  wire          i2c1_scl,
    input  wire          i2c1_sda,
    input  wire          i2c_scl0_IN,
    input  wire          i2c_scl0_IN_1,
    input  wire          i2c_scl0_IN_2,
    output wire          i2c_scl0_OE,
    output wire          i2c_scl0_OE_1,
    output wire          i2c_scl0_OE_2,
    input  wire          i2c_sda0_IN,
    input  wire          i2c_sda0_IN_1,
    input  wire          i2c_sda0_IN_2,
    output wire          i2c_sda0_OE,
    output wire          i2c_sda0_OE_1,
    output wire          i2c_sda0_OE_2,

After:
    output wire          i2c0_oe,
    input  wire          i2c0_scl,
    input  wire          i2c0_scl_IN,
    output wire          i2c0_scl_OE,
    output wire          i2c0_scl_OUT,
    input  wire          i2c0_sda,
    input  wire          i2c0_sda_IN,
    output wire          i2c0_sda_OE,
    output wire          i2c0_sda_OUT,
    input  wire          i2c1_scl,
    input  wire          i2c1_scl_IN,
    output wire          i2c1_scl_OE,
    output wire          i2c1_scl_OUT,
    input  wire          i2c1_sda,
    input  wire          i2c1_sda_IN,
    output wire          i2c1_sda_OE,
    output wire          i2c1_sda_OUT,
