MT6280 SIP_MDSP link fail.
[Solution]
Modify EXTSRAM_type_7() to switch $ram_disk_size become 0x40000 if it's MT6280
[Verification]
m sys_auto_gen on MT6280_EVB_R7R8_HSPA(SIP_MDSP).W12.17
and the generated EXTSRAM_FS maxsize becomes 0x40000 and dummy_end base is correct as well.
[Phase-in Branch]
MT6280_DVT_DEV
MODEM_DEV
[Version]

 * MS table size
 *
 * MS table size should be synchronized with user's requirement. The only one user is NVRAM.
 *
 * NVRAM_CUSTOM_CFG_MAX_RECORD_SECTOR_NUM defines the maximum record size in NVRAM
 * (in custom_nvram_config.h). NVRAM should call NOR_ResumeSectorState (by FS_Commit)
 * after it writes maximum NVRAM_CUSTOM_CFG_MAX_RECORD_SECTOR_NUM sectors with protection
 * mode to ensure the integrity of a record.
 *
 * MSTABLE_ENTRY_NUM number is based on the worst senario: All FAT entries of clusters
 * of logical sectors are located in different physical sectors. In other word, we need
 * to write additional N sectors to update FAT after we write N data sectors. The other
 * 1 sector is for directory entry update.
 *
 * TODO: Use auto-gen to compute most suitable MS table size. Because the number of
 * sectors for FAT may be smaller than NVRAM_CUSTOM_CFG_MAX_RECORD_SECTOR_NUM. For example,
 * 64KB disk only needs 1 sector to store FAT.
