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

Kernel test robot reports following sparse warnings:
>> drivers/misc/eeprom/idt_89hpesx.c:599:31: sparse: sparse:
   incorrect type in assignment (different base types) @@
   expected unsigned short [addressable] [assigned] [usertype]

   expected unsigned short [addressable] [assigned] [usertype]
   memaddr

   drivers/misc/eeprom/idt_89hpesx.c:599:31: sparse:
   restricted __le16 [usertype]

   .....

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
