fix(arm): correct RSE_CRYPTO_EXPORT_PUBLIC_KEY_SID

The RSE_CRYPTO_EXPORT_PUBLIC_KEY_SID macro does not match the definition
in RSE. A paired macro, TFM_CRYPTO_EXPORT_PUBLIC_KEY, in the RSE's
header (located in interface/include/tfm_crypto_defs.h) is defined as
0x206. This causes the TF-A test PLATFORM_TEST=rse-rotpk to fail.

Correct the definition of RSE_CRYPTO_EXPORT_PUBLIC_KEY_SID to make the
test pass.
