Subject: [PATCH] tee: fix crypto select

When selecting a crypto cipher, we also need to select the
subsystem itself:

WARNING: unmet direct dependencies detected for CRYPTO_SHA1
Depends on [m]: CRYPTO [=m]
Selected by [y]:
- TEE [=y] && (HAVE_ARM_SMCCC [=n] || COMPILE_TEST [=y] || CPU_SUP_AMD [=y])
Selected by [m]:
- CRYPTO_DEV_QAT [=m] && CRYPTO [=m] && CRYPTO_HW [=y]
- CRYPTO_DEV_MEDIATEK [=m] && CRYPTO [=m] && CRYPTO_HW [=y] && (ARM && ARCH_MEDIATEK || COMPILE_TEST [=y])
- CRYPTO_DEV_SAFEXCEL [=m] && CRYPTO [=m] && CRYPTO_HW [=y] && (OF [=y] || PCI [=y] || COMPILE_TEST [=y]) && HAS_IOMEM [=y]
- CRYPTO_DEV_CCREE [=m] && CRYPTO [=m] && CRYPTO_HW [=y] && OF [=y] && HAS_DMA [=y]
- CRYPTO_DEV_SP_CCP [=y] && CRYPTO [=m] && CRYPTO_HW [=y] && CRYPTO_DEV_CCP [=y] && CRYPTO_DEV_CCP_DD [=m] && DMADEVICES [=y]

Fixes: e33bcbab16d1 ("tee: add support for session's client UUID generation")

The regression was introduced in the soc tree, I'd pick this patch
up directly into that unless someone sees a problem
