crypto: caam - fix misspelled upper_32_bits

An endianess fix mistakenly used higher_32_bits() instead of
upper_32_bits(), and that doesn't exist:

drivers/crypto/caam/desc_constr.h: In function 'append_ptr':
drivers/crypto/caam/desc_constr.h:84:75: error: implicit declaration of function 'higher_32_bits' [-Werror=implicit-function-declaration]
  *offset = cpu_to_caam_dma(ptr);
