fix(esc_lan9252): 修复LAN9252 HBI访问模型和IRQ输出使能问题

- 修正HBI访问模型：将ESC核心CSR(0x0000-0x0FFF)改为通过ECAT_CSR_CMD/DATA
  间接端口访问，解决此前直接寻址导致核心寄存器恒读0/写丢弃的问题

- 新增csrRead/csrWrite/pramRead/pramWrite接口，正确实现LAN9252访问端口操作

- 添加PDI就绪检测：等待DL_STATUS bit0置位确认EEPROM加载完成和EtherCAT核心使能

- 实现IRQ引脚输出使能：配置IRQ_CFG和INT_EN寄存器，使EtherCAT事件能到达PB1，
  解决PDI_Isr未触发导致SAFEOP->OP无限挂起的问题

- 为ESC_EXMC硬件诊断添加CONFIG_ESC_EXMC_DIAG门控，默认关闭避免影响正常运行

- 修正system_gd32e50x.c中HXTAL故障诊断的寄存器偏移和位设置错
