Revert "crypto: poly1305 - cleanup stray CRYPTO_LIB_POLY1305_RSIZE"

This reverts commit 8bdc2a190105e862dfe7a4033f2fd385b7e58ae8.

It got merged a bit prematurely and shortly after the kernel test robot
and Sudip pointed out build failures:

arm: imx_v6_v7_defconfig and multi_v7_defconfig
mips: decstation_64_defconfig, decstation_defconfig, decstation_r4k_defconfig

In file included from crypto/chacha20poly1305.c:13:
include/crypto/poly1305.h:56:46: error: 'CONFIG_CRYPTO_LIB_POLY1305_RSIZE' undeclared here (not in a function); did you mean 'CONFIG_CRYPTO_POLY1305_MODULE'?
56 | struct poly1305_key opaque_r[CONFIG_CRYPTO_LIB_POLY1305_RSIZE];
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

We could attempt to fix this by listing the dependencies piecemeal, but
it's not as obvious as it looks: drivers like caam use this macro in
headers even if there's no .o compiled in that makes use of it. So
actually fixing this might require a bit more of a comprehensive
approach, rather than whack-a-mole with hunting down which drivers use
which headers which use this macro.

Therefore, this commit just reverts the change, and maybe the problem
can be visited on the next rainy day.
