hw/misc/aspeed_scu: Fix AST2600_RNG definitions

Commit e09cf36321f6 ("hw: aspeed_scu: Add AST2600 support") introduced a typo on the definitions of the Random Number Generator registers. Fix that. The implementation of RNG_CTRL and RNG_DATA should be rechecked on HW since the QEMU implementation always generates random data, regardless of RNG_CTRL. A comment in aspeed_ast2600_scu_read() admits uncertainty about the behavior : /* * On hardware, RNG_DATA works regardless of the state of the * enable bit in RNG_CTRL * * TODO: Check this is true for ast2600 */ Resolves: https://gitlab.com/qemu-project/qemu/-/work_items/2350 Fixes: e09cf36321f6 ("hw: aspeed_scu: Add AST2600 support") Reviewed-by: Jamin Lin <jamin_lin@aspeedtech.com> Signed-off-by: Cédric Le Goater <clg@redhat.com>
