Apply some optimizations to speed up bitstream loading (both for full and split periph/core bitstreams):
Change the size of the first fs read, so that all the subsequent reads are aligned to a specific value (called MAX_FIRST_LOAD_SIZE). This value was chosen so that in subsequent reads the fat fs driver doesn't have to allocate a temporary buffer in get_contents (assuming 8KiB clusters).
Change the buffer size to a larger value when reading to ddr (but not too large, because large transfers cause a stack overflow in the dwmmc driver).
