[U-Boot] [Patch V6 1/4] spi: fsl_qspi: fix compile warning for 64-bit platform

[Gong Qianyu]

From: Gong Qianyu <Qianyu.Gong at freescale.com>

This patch fixes the following compile warning:
drivers/spi/fsl_qspi.c: In function 'fsl_qspi_probe':
drivers/spi/fsl_qspi.c:937:15:
  warning: cast to pointer from integer of different size
					 [-Wint-to-pointer-cast]
  priv->regs = (struct fsl_qspi_regs *)plat->reg_base;
               ^
Just make the cast explicit.
