drm/tyr: specify base type for registers

This commit updates all register definitions to explicitly use the TyrRegisters
base type in the register! macro invocations.

[Severity: Medium]
The commit message states that all registers are updated to use the new base
type, but it looks like a few register! invocations were missed during the
conversion.

For instance, earlier in this same file (drivers/gpu/drm/tyr/regs.rs), the
LOCKADDR register block doesn't have the new base parameter:

        register! {
            /// Lock region address for each address space.
            pub(crate) LOCKADDR(u64)[MAX_AS, stride = STRIDE] @ 0x2410 {
                /// Lock region size.
                5:0     size;

Additionally, the SectionFlags register in drivers/gpu/drm/tyr/fw.rs was also
missed by this patch:

    register! {
         #[allow(non_upper_case_globals)]
        pub(super) SectionFlags(u32) @ 0x0 {
            0:0 read => bool;

Were these intentionally left with the default base type, or were they 
overlooked during the refactoring?
