i2c: pxa: Fix Wvoid-pointer-to-enum-cast warning

Browse Source 
'i2c_types' is an enum, thus cast of pointer on 64-bit compile test with
clang and W=1 causes:

  i2c-pxa.c:1269:15: error: cast to smaller integer type 'enum pxa_i2c_types' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

One of the discussions in 2023 on LKML suggested warning is not suitable
for kernel.  Nothing changed in this regard since that time, so assume
the warning will stay and we want to have warnings-free builds.
