Field writer has no impl when enumeratedValue is derived across peripherals

[kaizensparc]

Hello,
I'm currently implementing a PAC/HAL for the GD32E103 device and set the SVD to derive TIMER*.CTL0.CEN registers to TIMER0.CTL0.CEN register:

            <field>
              <name>CEN</name>
              <description>Counter enable</description>
              <bitOffset>0</bitOffset>
              <bitWidth>1</bitWidth>
              <enumeratedValues derivedFrom="TIMER0.CTL0.CEN.CEN"/>
            </field>

The generated code reuses the CEN_A and CEN_R types from TIMER0 to every timer but not the CEN_W. The issue is that is defines the type (pub type CEN_W<'a, const O: u8> = crate::BitWriter<'a, u32, CTL0_SPEC, CEN_A, O>;) but it does not provides its implementation (to set the variants) as it does on TIMER0.

This issue appeared between svd2rust 0.24.0 and 0.25.0.

An example of the bug is available on https://github.com/gd32-rust/gd32-rs for the gd32f1 timer peripheral (the gd32e1 is still a WIP). The generated source code is available on https://github.com/gd32-rust/gd32-rs-nightlies/tree/main/gd32f1. I attached the patched svd used by svd2rust for generation. On the svd file you can see lines 17899-17905 the derived I quoted earlier.
On the generated code you can compare the two CEN_W types for TIMER0 and TIMER1 (which is derived from TIMER0). The documentation for TIMER0.CTL0.CEN is on https://docs.rs/gd32f1/latest/gd32f1/gd32f130/timer0/ctl0/type.CEN_W.html and has the implementation. The one for TIMER1.CTL0.CEN is on https://docs.rs/gd32f1/latest/gd32f1/gd32f130/timer1/ctl0/type.CEN_W.html and lacks the implementation.
