[PATCH] tee: fix crypto select

[Arnd Bergmann]

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]

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