[bsp][n32] n32h497zgl7-evb: add SDRAM port and correct Kconfig defaults

drv_sdram.c includes <sdram_port.h> unconditionally under BSP_USING_SDRAM,
and n32h497zgl7-evb had no such header, so the option could not build at
all. Add one for the M12L64164A fitted on this board: 4 banks x 1M x 16
bits = 8 MB, 12 row address bits, 8 column address bits, SDRAM1 mapped at
0x98000000. The timing values are the ones validated on this board in
hardware.

Three of the Kconfig defaults described a different part:

  BSP_SDRAM_DATA_WIDTH_SEL   default 32 -> 16
  BSP_SDRAM_COLUMN_BITS_SEL  default 9  -> 8
  BSP_SDRAM_SIZE             default 32 -> 8

BANK1, ROW_BIT_12 and CAS_LATENCY_3 already matched and are unchanged.

Verified by building n32h497zgl7-evb with BSP_PERIPH_PIN_CFG_READY and
BSP_USING_SDRAM enabled: drv_sdram.c and the SDK's n32h49x_sdram.c compile
and link with no warnings.
