ARM: unify asm/arm-smccc.h and linux/arm-smccc.h
Since 2c20674f0c ("ARM: Add code to support SMCCC on AArch64") we have both arch/arm/include/asm/arm-smccc.h and include/linux/arm-smccc.h. The latter was introduced with Kernel commit 680a0873e ("arm: kernel: Add SMC structure parameter") included, so we have to add the parameter for ARM32 aswell. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
