misc: Kconfig: exclude mrvl-cn10k-dpi compilation for 32-bit systems 



Upon adding CONFIG_ARCH_THUNDER & CONFIG_COMPILE_TEST dependency,
compilation errors arise on 32-bit ARM with writeq() & readq() calls
which are used for accessing 64-bit values.

Since DPI hardware only works with 64-bit register accesses, using
CONFIG_64BIT dependency to skip compilation on 32-bit systems.
