[PATCH 30/30] imx: fsl_sec: preprocessor casting issue with addresses involving math

[Peng Fan (OSS)]

From: Utkarsh Gupta <utkarsh.gupta at nxp.com>

The sec_in32 preprocessor is defined as follows in include/fsl_sec.h file:
When address "a" is calculated using math for ex: addition of base address and
an offset, then casting is applied only to the first address which in this
example is base address.

caam_ccbvid_reg = sec_in32(CONFIG_SYS_FSL_SEC_ADDR + CAAM_CCBVID_OFFSET)
resolves to:
caam_ccbvid_reg = in_le32((ulong *)(ulong)CONFIG_SYS_FSL_SEC_ADDR +
 CAAM_CCBVID_OFFSET)
instead it should resolve to:
caam_ccbvid_reg = in_le32((ulong *)(ulong)(CONFIG_SYS_FSL_SEC_ADDR +
 CAAM_CCBVID_OFFSET))

Thus add parenthesis around the address "a" so that however the address is
calculated, the casting is applied to the final calculated address.
