misc: eeprom/idt_89hpesx: Convert data structures to LE explicitly

Kernel test robot reports following sparse warnings:

   .....

For data structures needs cpu_to_le* conversion, their prototype need
to be declared with __le* explicitly.

Declare data structures to __le* explicitly to address the issue:
- struct idt_eeprom_seq::memaddr
- struct idt_csr_seq::csraddr
- struct idt_csr_seq::data
