Arrays are not always expanded resulting in invalid subtype declarations.

Running svd2ada on (for example) https://github.com/espressif/svd/blob/main/svd/esp32s3.svd does not always handle arrays correctly.

Taking the excerpt:

<register>
          <name>INT_RAW</name>
          <description>Raw interrupt status</description>
          <addressOffset>0x70</addressOffset>
          <size>0x20</size>
          <fields>
            <field>
              <dim>4</dim>
              <dimIncrement>0x1</dimIncrement>
              <dimIndex>0-3</dimIndex>
              <name>CH%s_TX_END</name>
              <description>The interrupt raw bit for CHANNEL%s. Triggered when transmission done.</description>
              <bitOffset>0</bitOffset>
              <bitWidth>1</bitWidth>
              <access>read-write</access>
            </field>
            <field>
              <dim>4</dim>
              <dimIncrement>0x1</dimIncrement>
              <dimIndex>0-3</dimIndex>
              <name>CH%s_TX_ERR</name>
              <description>The interrupt raw bit for CHANNEL%s. Triggered when error occurs.</description>
              <bitOffset>4</bitOffset>
              <bitWidth>1</bitWidth>
              <access>read-write</access>
            </field>

Will create:

subtype INT_RAW_CH%s_TX_END_Field is ESP32-S3.Bit;
  subtype INT_RAW_CH%s_TX_ERR_Field is ESP32-S3.Bit;
  subtype INT_RAW_CH%s_TX_THR_EVENT_Field is ESP32-S3.Bit;
  subtype INT_RAW_CH%s_TX_LOOP_Field is ESP32-S3.Bit;
  subtype INT_RAW_CH%s_RX_END_Field is ESP32-S3.Bit;
  subtype INT_RAW_CH%s_RX_ERR_Field is ESP32-S3.Bit;
  subtype INT_RAW_CH%s_RX_THR_EVENT_Field is ESP32-S3.Bit;
  subtype INT_RAW_TX_CH3_DMA_ACCESS_FAIL_Field is ESP32-S3.Bit;
  subtype INT_RAW_RX_CH7_DMA_ACCESS_FAIL_Field is ESP32-S3.Bit;

--  Raw interrupt status
  type INT_RAW_Register is record
     --  The interrupt raw bit for CHANNEL%s. Triggered when transmission
     --  done.
     CH%s_TX_END            : INT_RAW_CH%s_TX_END_Field := 16#0#;
     --  unspecified
     Reserved_1_3           : ESP32-S3.UInt3 := 16#0#;
     --  The interrupt raw bit for CHANNEL%s. Triggered when error occurs.
     CH%s_TX_ERR            : INT_RAW_CH%s_TX_ERR_Field := 16#0#;
     --  unspecified
     Reserved_5_7           : ESP32-S3.UInt3 := 16#0#;
     --  The interrupt raw bit for CHANNEL%s. Triggered when transmitter sent
     --  more data than configured value.
     CH%s_TX_THR_EVENT      : INT_RAW_CH%s_TX_THR_EVENT_Field := 16#0#;
     --  unspecified

Reproduce the issue with svd2ada and the esp32s3.svd example linked in the report, then trace how array fields are expanded into subtype declarations and register records. The fix is complete when the generated declarations no longer contain literal % placeholders and remain valid for the shown SVD input.
