[PATCH v5 03/25] target/riscv: Fix size of pc, load_[val|res]

[Anton Johansson via <qemu-devel@nongnu.org>]

Fix to 64 bits in size and as these are mapped to TCG globals, be
careful with host endianness when allocating globals.  Casts are
added to logging expressions to retain the correct size for
TARGET_RISCV32.
